What are the properties of exponents?

The properties of exponents include the product rule (a^m * a^n = a^(m+n)), the quotient rule (a^m / a^n = a^(m-n)), the power rule ((a^m)^n = a^(m*n)), the zero exponent rule (a^0 = 1), the negative exponent rule (a^(-n) = 1/a^n), and the rule for powers of one (a^1 = a). These rules help simplify and manipulate expressions involving exponents.

How does factoring help simplify algebraic expressions?

Factoring helps simplify algebraic expressions by breaking down complex expressions into simpler forms that are easier to work with. It allows us to find common factors in terms of variables and numbers, which can reduce the overall complexity of the expression and make it easier to manipulate. Factoring also helps us identify patterns or relationships within the expression, leading to a more efficient and structured approach to solving algebraic problems.

What is the quadratic formula used for?

The quadratic formula is used to find the roots of a quadratic equation, which are the values of x where the equation equals zero. This formula is particularly useful in solving equations of the form ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable. By using the quadratic formula, we can quickly and accurately determine the solutions to these types of equations.

What are the key features of a graph of a quadratic function?

The key features of a graph of a quadratic function include a parabolic shape, a vertex that represents the minimum or maximum point of the function, and symmetry about the axis of symmetry. The axis of symmetry divides the parabola into two equal halves, and the direction of opening of the parabola depends on the leading coefficient of the quadratic function. Additionally, the x-intercepts of the graph represent the solutions to the quadratic equation, while the y-intercept is the point where the graph intersects the y-axis.

How do you solve systems of equations using substitution?

To solve a system of equations using substitution, you need to solve one of the equations for a variable in terms of the other variable, and then substitute that expression into the other equation. This will create a new equation with only one variable, which you can then solve to find the value of that variable. Once you have found the value of one variable, you can substitute it back into one of the original equations to solve for the other variable. This process allows you to find the unique solution to the system of equations.

What is the difference between arithmetic and geometric sequences?

Arithmetic sequences have a constant difference between consecutive terms, while geometric sequences have a constant ratio between consecutive terms. In arithmetic sequences, each term is obtained by adding or subtracting the same number from the previous term, while in geometric sequences, each term is obtained by multiplying or dividing the previous term by the same number.

How do you find the inverse of a function?

To find the inverse of a function, you swap the input and output variables and then solve for the new output variable. This involves switching the dependent and independent variables in the original function, then solving the resulting equation for the new dependent variable. This process essentially reverses the original function's operation, allowing you to find the function's inverse.

What is the significance of the discriminant in solving quadratic equations?

The discriminant in quadratic equations, which is the part of the quadratic formula under the square root sign (b^2 - 4ac), helps determine the nature of the roots of the equation. If the discriminant is positive, the equation has two real and distinct roots. If the discriminant is zero, the equation has one real root. If the discriminant is negative, the equation has complex roots. Therefore, the discriminant is critical in determining the number and type of solutions to a quadratic equation.

How do you graph rational functions and identify asymptotes?

To graph rational functions and identify asymptotes, first factor the numerator and denominator to find any common factors that can be simplified or canceled out. Next, set the denominator equal to zero to find vertical asymptotes. Then, divide the numerator by the denominator and check for horizontal or slant asymptotes by comparing the degrees of the polynomials. Plot these asymptotes on the graph and include any x or y-intercepts. Finally, sketch the curve by plotting additional points and checking the behavior of the function as it approaches the asymptotes.

What are the steps to solve a logarithmic equation?

To solve a logarithmic equation, first isolate the logarithmic expression on one side of the equation. Then, rewrite the equation in exponential form to eliminate the logarithm. Solve for the variable using basic algebraic operations. Finally, check your solution by substituting it back into the original equation to ensure it satisfies all restrictions and accurately solves the logarithmic equation.
