What is the parent function of a linear function?

The parent function of a linear function is the identity function, which can be written as f(x) = x. It represents a straight line with a slope of 1 and passes through the origin. Any linear function can be obtained by transforming this basic function through changes in slope or intercept.

How would you describe the parent function of a quadratic function?

The parent function of a quadratic function is a simple quadratic equation in the form of f(x) = x^2. It is a parabola that opens upwards, with a vertex at the origin (0,0) and symmetrical around the y-axis. The graph of the parent quadratic function is a smooth curve that represents the basic shape and behavior of all quadratic functions, which can be transformed through shifts, stretches, and reflections to create different specific quadratic equations.

What is the parent function of an absolute value function?

The parent function of an absolute value function is y = |x|, where the output is the absolute value of the input.

How would you describe the parent function of a square root function?

The parent function of a square root function is y = ?x, where the output (y) is the square root of the input (x). This function is characterized by having a square root symbol (?) and an index of 2, indicating that it is a radical function. The graph of a square root function is a curve that starts at the origin (0,0) and gradually increases as x values increase, resulting in a non-linear relationship between x and y values.

What is the parent function of a cubic function?

The parent function of a cubic function is f(x) = x^3.

How would you describe the parent function of an exponential function?

The parent function of an exponential function is typically written as f(x) = b^x, where b is a positive real number not equal to 1. The graph of this function starts at the point (0,1) and increases rapidly as x moves to the right. It is characterized by continuous growth or decay, depending on whether the base b is greater than 1 or between 0 and 1.

What is the parent function of a logarithmic function?

The parent function of a logarithmic function is f(x) = logb(x), where b is the base of the logarithm.

How would you describe the parent function of a rational function?

The parent function of a rational function is f(x) = 1/x. This function represents the most basic form of a rational function, where the output is the reciprocal of the input. It consists of two parts: a numerator (1) and a denominator (x), and it has a vertical asymptote at x=0 and horizontal asymptote at y=0. The parent function of a rational function serves as a starting point for understanding how changes in coefficients, exponents, and constants can transform the graph of a rational function.

What is the parent function of a sine function?

The parent function of a sine function is f(x) = sin(x), which represents the basic sinusoidal wave that oscillates between -1 and 1 along the y-axis as x varies.

How would you describe the parent function of a cosine function?

The parent function of a cosine function is a periodic wave-like function that oscillates between 1 and -1, with the peaks (maximum values) occurring at intervals of ?/2 and the troughs (minimum values) occurring at intervals of ?. It has a period of 2? and is symmetrical about the y-axis.
