Answer:
The range: { -11, 11, 24}
Step-by-step explanation:
f(x) = 5x + 9 Substitute each number in the domain, which is the x-value, in the equation and solve.
f(-4) = 5(-4) + 9 ; f(-4) = -20 + 9; f(-4) = -11
f(2/5) = 5(2/5) + 9; f(-2/5) = 10/5 + 9; f(2/5) = 2 + 9; f(2/5) = 11
f(3) = 5(3) + 9; f(3) = 15 + 9; f(3) = 24
The range: { -11, 11, 24}
