What is the pattern in the sequence: 2, 4, 6, 8, ...

The pattern in the sequence is that each subsequent number is increasing by 2. So, the next number in the sequence would be 10, then 12, and so on.

What is the next term in the sequence: 3, 6, 9, 12, ...

The next term in the sequence is 15. Each term increases by 3.

Determine the rule for the linear function given the points (2, 5) and (4, 11).

To determine the rule for the linear function, you can first find the slope by using the formula (y2 - y1) / (x2 - x1) with the points (2, 5) and (4, 11), which will give you a slope of 3. Then, use the slope-intercept form of a linear equation, y = mx + b, where m is the slope. Substitute one of the points to solve for b, leading to the equation y = 3x - 1 as the rule for the linear function.

Solve the equation: 3x + 5 = 17.

To solve the equation 3x + 5 = 17, we need to isolate the variable x. First, we subtract 5 from both sides to get 3x = 12. Then, we divide both sides by 3 to find that x = 4. Therefore, the solution to the equation is x = 4.

Simplify the expression: 2(x + 3) - 4x.

The simplified expression is 2x + 6 - 4x, which simplifies further to -2x + 6.

Find the x-intercept of the quadratic function f(x) = x^2 - 4x + 3.

To find the x-intercept of the quadratic function f(x) = x^2 - 4x + 3, set f(x) equal to zero and solve for x. So, x^2 - 4x + 3 = 0. By factoring the quadratic equation, we get (x - 1)(x - 3) = 0. Setting each factor to zero gives x = 1 and x = 3. Therefore, the x-intercepts of the function f(x) are x = 1 and x = 3.

Determine the domain and range of the function y = 2/x.

The domain of the function y = 2/x is all real numbers except x = 0, as the denominator cannot be zero. Therefore, the domain is (-?, 0) U (0, ?). The range of the function is all real numbers except y = 0, as the function cannot equal zero. Therefore, the range is (-?, 0) U (0, ?).

Identify the vertex of the parabola defined by the quadratic function f(x) = (x - 2)^2 + 3.

The vertex of the parabola defined by the quadratic function f(x) = (x - 2)^2 + 3 is located at the point (2, 3). This is because in the equation of a parabola in vertex form, y = a(x - h)^2 + k, the vertex is at the point (h, k). In this case, h = 2 and k = 3, so the vertex is at (2, 3).

Solve the system of equations: x + y = 7 and 3x - y = 5.

To solve the system of equations x + y = 7 and 3x - y = 5, we can first add the two equations to eliminate y, yielding 4x = 12, so x = 3. Substituting x = 3 back into the first equation x + y = 7 gives 3 + y = 7, which simplifies to y = 4. Therefore, the solution to the system of equations is x = 3 and y = 4.

Given the exponential function f(x) = 2(3)^x, find f(2).

To find f(2), we simply plug in x=2 into the exponential function f(x) = 2(3)^x. Substituting x=2, we get f(2) = 2(3)^2 = 2(9) = 18. Therefore, f(2) equals 18.
