Question

f(x)=2x²+19x+35 and g(x)=-x-7

Which answer choices are true? Select all that apply.

a. f-g=2x²+20x+42

b. f/g=-2x-5

c. g(f(-3))=-11

d. g(x): As x ➔ ∞, y ➔ -∞



Answer 1

a, b and d are true

c a little off

f(-3) =18-57+35 = -4

g(f(-3)) = -(-4)-7 = 4-7 = -3, not -11, close though, except for a sign
