How do you use f (x)= 2x - 3 and g(x)= 1-x^2 to evaluate f(g(0))?

See the full process for evaluating these functions below.

Explanation:

First, evaluate g(0):

If g(color(red)(x)) = 1 - x^2, then

g(color(red)(0)) = 1 - 0^2

g(color(red)(0)) = 1 - 0

g(0) = 1

Second, evaluate f(g(0)):

If f(color(red)(x)) = 2x - 3 and g(0) = 1, then

f(g(0)) = f(1)

and

f(color(red)(1)) = (2 xx 1) - 3

f(color(red)(1)) = 2 - 3

f(color(red)(1)) = -1

Therefore

f(g(0)) = -1
