If f(x) = x2 + 6x + 10, find f(x - 2)

Question

If f(x) = x2 + 6x + 10, find f(x - 2)

Answer 1

This means that you plug in an (x-2) wherever you see x.

 

So you're equation before simplifying it is:

f(x-2)=(x-2)^2 + 6(x-2) + 10

 

Now you should foil and simplify and end up with:

x^2 - 4x + 4 + 6x - 12 + 10

 

and your final would be:

 

x^2 + 2x + 2
