Question

Let f(x) = x^2 +5 and G (x) = X+5/x. Find (gof)(-3)

a.) 1/4 <------
b.) 14/19
c.) 19/14
d 49/9
Check answers please

Answer 1

C

Step-by-step explanation:is the correct anwser

Answer 2

(gof)(-3) means the composition of two functions at x = -3.

(gof)(-3) can also be expressed as g(f(-3))

So, first we find f(-3)

f(x) = x² + 5

f(-3) = 9 + 5 = 14

g(f(-3)) = g(14)

g(14) = (14+5)/14 = 19/14

Thus, option C gives the correct answer
