Question

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(−5).

a. 104

b.−246

c.250

d.146

Answer 1

Hi! the answer should be 104

----

Formula: h(g(x))

1) First you want to take the -5 and plug that into the given equation for g(x)

• 2(-5)= -10

2) Next you want to take the -10 and plug it into the equation for h(x)

• (-10)²+4= 104
