Answer and step-by-step explanation:
Please look at the picture above for the solutions.
Substitute the given values of x to the function g(x) then simplify.
For b and c, use the FOIL method and the distributive property of multiplication to simplify. The arrows are guide for you to understand it more clearly.
a. g(2) = -4
b. g(a + b) = a^2 + 2ab + b^2 - 4a - 4b
c. g(2 - x) = x^2 - 4
