all ok
good work
Can you please check my answers for these questions? I'm having a little trouble with my signs, because I sometimes substitute in wrong, so I get these wrong because of that, Thank you!
For the following problems, use f(x) = x^2+ 3;
g(x) = –3x; h(x) = 8x - 5;
a. (f + h)(x) = [My answer= x^2+8x-2]
b. (g – h)(x) = [My answer= -11x+5]
c. (f + g)(3) = [My answer= 3]
d. (f ∘ g)(–2) = [My answer= 39]
e. (fg)(2x) = [My answer= -24x^3-18x]
