3. Find f[h(a+4)], given the functions below. * Given f(x) = 5x, g(x) = -2x + 1, and h(x) = x2 + 6x + 8, find each value.
O A 2a^2 +15a +120
O B 5a^2 +30a +240
O C 5a^2 +70a +240
O D-5a^2 +50a +360

C 5a^2 +70a +240

Step-by-step explanation:

We have given these following functions:

h(a+4)

This function is:

f[h(a+4)]

Thus

The correct answer is given by option C.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
