Question 1144236: Can someone help? Thank you.
When given f(x)=2x^2+4x-1, evaluate and simplify f(z+3).
Would I plug in z to x in the original equation?

You can put this solution on YOUR website! When given f(x)=2x^2+4x-1, evaluate and simplify f(z+3).

------------------
Wherever there's an x, sub (z+3)

You can put this solution on YOUR website! .
As Alan said, plug in "z+3" instead of "x" at every occurrence of "x".
In the given case, it works this way:
f(z+3) = 2*(z+3)^2 + 4*(z+3) - 1.
Next, you must simplify it.
It is simple job, and I leave it to you to complete it.
In order for to get full understanding, you should complete it on your own at least once.
