If f(x) = 3(x+5) + 4/x, what is f(a + 2)? A. 3(a + 2) + 4/a +2
B. 3(f(a)+5)+ 4/f(a)+2
C. 3(a + 7) + 4/a+2

C. 3(a+7) + 4/a+2

Step-by-step explanation:

f(x) = 3(x+5) + 4/x

f(a+2) = 3(a+2+5) + 4 /(a+2)

= 3(a+7) + 4/a+2

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
