Question

Which of the following is a parent function

a)f(x)=4x^2
b)f(x)=4^x
c)f(x)= -2^x+1
d)f(x)=e^3x -2

Answer 1

f(x) = 4^x

Explanation:

Answer 2

`\bf 4x^2\impliedby x^2\textit{ with a shrink factor of }(1)/(4) \\\\\\ -2^(x+1)\impliedby 2^x\textit{ flipped upside-down with a horizontal shift of +1} \\\\\\ e^(3x-2)\impliedby e^x\textit{ with a vertical shrink of }(1)/(3)\textit{ and a horizonta shift of -2}`

there's one left out, reason why, is because is has no shifts or stretches or any other transformations, because is a parent function, and should be obvious by its absence.
