Question

Find the range of each function for the given domain.
18. f(x) = 2x – 7;{-2, -1,0, 1, 2}
19. g(x) = -4x + 1;{-5, -1,0, 2, 10}

Answer 1

Answer:

{-11, -9, -7, -5, -3}

{-19, -3, 1, 9, 41}

Step-by-step explanation:

Range of f(x) will be

{2(-2)-7 ,2(-1)-7, 2(0)-7, 2(1) – 7, 2(2) – 7}

{-11, -9, -7, -5, -3}

Range of g(x) will be

{4(-5)+1 ,4(-1)+1, 4(0)+1, 4(2)+1, 4(10)+1}

{-19, -3, 1, 9, 41}
