Question

Solve the equation for y in terms if x, and replace y with functions notation f(x). Then find f(3).
y+4x^2=4
f(x)=

Answer 1

\[y=4-4x^2\] is a start

Answer 2

I dont understand where to go from there

Answer 3

write
\[f(x)=4-4x^2\] and you are done

Answer 4

so to find f(3) I just replace x with 3

Answer 5

yes
