Question

If g(x) = 4x - 3 and h(x) = -4x, what is g(5) + h(3)?

Answer 1

g(5) + h(3) = 5

Explanation:

g(5)

`g(5) = 4(5) - 3\\\rule{150}{0.5}\\g(5) = 20 - 3\\\\\boxed{g(5)=17}`

h(3)

`h(3) = -4(3)\\\rule{150}{0.5}\\\boxed{h(3) = -12}`

g(5) + h(3)

`17 + -12\\\rule{150}{0.5}\\17 - 12\\\\\boxed{5}`

Hope this helps.
