Evaluate the function at each specified value of the independent variable and simplify

Question

g(y) = 7 - 3y

a) g(0) b) g(7/3) c) g(s+2)

Answer 1

Just plug in the variable into the equation

g(0) = 7 - 3 * 0

g(0) = 7

g(7/3) = 7 - 3 * (7/3)

g(7/3) = 0

g(s+2) = 7 - 3(s+2)

g(s+2) = 7 - 3s - 6

g(s+2) = 1 - 3s
