Answer:
The answer to your question is:
a) f(a) -2 = a² - 3
b) f(a - 2) = a² - 4a + 3
c) f(b + d) = b² + 2bd + d² - 1
Step-by-step explanation:
a. f(a) - 2 = (a)² - 1 - 2
f(a) -2 = a² - 3
b. f(a - 2) = (a - 2)² - 1
f(a - 2) = a² - 4a + 4 - 1
f(a - 2) = a² - 4a + 3
c. f(b + d) = (b + d)² - 1
f(b + d) = b² + 2bd + d² - 1
