Question 329096: 15. If f(x) =2x2+1 and g(x)=x-3, find (f o g)(x).
a. (f o g)(x) = 2x 2 - 17
b. (f o g)(x) = 2x 2 - 12x + 19
c. (f o g)(x) = 2x 2 - 2
d. (f o g)(x) = 2x 2 - 12x + 13
* I did fog(x)=f{g(x)}=fx-3)=2x2+1=2{x-3}^2+1=4x^2-24x+37.
But thats not a answer choice. Stuck!!!

You're correct up to expanding the function,

The leading coefficient should be a 2 and not a 4.
You seem to have doubled up somehow.
