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
