Question

Let f(x) = 5x – 4 and g(x) = x² – 1. Find each value.

(gºf)(-1)
(fºg)(2)
(gºf)(0)
f(g(16)
f(g(0))
g(f(4/5))

Answer 1

35.) 80

36.) 11

37.) 15

38.) 21

39.) -9

40.) -1

Explanation:

In simplified terms the question is asking

35.) g(f(-1)) =

g(-9) = 80

36.) f(g(2)) =

f(3) = 11

37.) g(f(0)) =

g(-4) = 15

38.) f(g(root6)) =

f(5) = 21

39.) f(g(0)) =

f(-1) = -9

40.) g(f(4/5)) =

g(0) = -1
