Solving (a): (g + f)(2)
This is calculated as:
Calculate g(2) and f(2)
So:
Solving (b):
This is calculated as:
Calculate f(-1) and g(-1)
So:
Solving (c): (g - f)(-1)
This is calculated as:
Calculate g(-1) and f(-1)
So:
Solving (d): (g * f)(2)
This is calculated as:
Calculate g(2) and f(2)
So:
B) (-mn)^3 (-1)^3m^3n^3 -m^3n^3
Answer:
D: Subtract 3 from both sides
