Question

Which of the following is the linear parent function?

A. Fx) = x
B. Fx) =1/x
C. F(x) = |x|
D. F(x) = x^3

Answer 1

A linear parent function is the equation y = x or f(x) = x. A parent function is the simplest equation of a function. Thus, f(x) = x is the simplest of all linear functions and that is the reason why it is called linear parent function

Answer 2

F(x) = x

Explanation:

A line is of the form

x to the first power

1/x is not x to the first power and makes a curve

|x| makes a v shape

x^3 is a curve
