Question

Which of these is the quadratic parent function?

A. f(x) = (1/4 x)²
B. f(x)=x²-3
C. f(x) = x² +5
D. f(x) = x²

Answer 1

`f(x)=x^2`

Explanation:

The quadratic parent function, has no transformations, and has the vertex at (0, 0). Which is the function:
`f(x)=x^2`. Any other quadratic function, has some form of transformation, whether it be a reflection, translation, compression/stretch, etc...
