# Algebra II Funtion

posted by .

f(x)=x-11 f(4)
f(4)=4-11
f(4)=-7

This is my work for this function. Is it correct? And can you help me solve the next one?

f(x) =9x3 - x2 + 2 ; f(2)

Substitute f(4) = -7 into the equation for f(x):

f(x) = x - 11 * (-7)
f(x) = x + 77

f(x) =9x3 - x2 + 2 ; f(2)
For this one, f(2) means find the value of f(x) when x = 2, so just put 2 into the equation for f(x) and solve

The way you typed the first question caused Jennifer to misunderstand the problem

If you meant , find f(4) when f(x) = x-11
then you were correct

Oh, okay. Sorry for the confusion! And thank you for the help.
