Algebra II Funtion

f(x)=x11 f(4)
f(4)=411
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) = x11
then you were correct 
Oh, okay. Sorry for the confusion! And thank you for the help.
