Answer:
f•g(-3) = 5 and g•f(-3) = 173
Explanation:
f•g(-3):
1. Apply function g to x = -3 to get y = 2(-3) + 5 = -1.
2. Apply function f to y = -1 to get z = 4(-1)^2 - (-1) = 5.
g•f(-3):
1. Apply function f to x = -3 to get y = 4(-3)^2 - (-3) = 83.
2. Apply function g to y = 83 to get z = 2(83) + 5 = 173.
Therefore, f•g(-3) = 5 and g•f(-3) = 173 .
In short, function composition is when you apply one function to the output of another function.
