For the following exercises, use each pair of functions to find f(g(0)) and g(f(0)). f(x) = 4x + 8, g(x) = 7 - x^2 f(x) = 5x + 7, g(x) = 4 - 2x^2

Solution

72)f(x)=4x+8,g(x)=7-x²

f(0)=8,g(0)=7

f(g(0))

=f(7)

=4(7) +8

=28+8

=36

g(f(0))

=g(8)

=7-8²

=7-64

=-57

=================================================

73)

f(x)=5x+7,g(x)=4-2x²

f(0)=7,g(0)=4

f(g(0))

=f(4)

=(5*4)+7

=20+7

=27

g(f(0))

=g(7)

=4-2(7)²

=4-2(49)

=4-98

=-94
