Question

Given f(x) = 2x + 1 and g(x) = 3x + 5,

find h(x) = f(x) ∙ g(x).

h(x) = 5x + 6

h(x) = 6x2 + 13x + 5

h(x) = 6x2 + 7x + 5

h(x) = 10x + 12

Answer 1

`6 {x}^(2) + 13x + 5`

Explanation:

`f(x) = 2x + 1 \\ g(x) = 3x + 5 \\ </p><p></p><p>find \: \: \: h(x) = f(x) ∙ g(x) \\ \\ \\ h(x) = (2x + 1)(3x + 5) \\ = 6 {x}^(2) + 10x + 3x + 5 \\ = 6 {x}^(2) + 13x + 5`

unless it's a composition of functions instead of multiplication...
