Question

Given the following function, find f(x + 3).
find f(x+3)

Answer 1

2x^2-6x

Answer 2

replace 'x' with 'x+3' in the function and expand.

Answer 3

...or don't expand. Just substitute.

If your classroom experience has demanded "expanding" and/or "simplifying", then please comply with these demands. If not, just substitute.

Answer 4

=2x^2+6x

Answer 5

\(f(x) = 2x^{2} + 6x\) -- We've established that.

We need \(f(x+3)\). Do you know how to find that?
