F(x) = 3x + 4 + 2
g(x) = 4
Find (f + g)(x).

How do you determine whether a relationship represented as as graph is linear or nonlinear

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)

Having a hard time understanding this question (see attachment).
