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:

18. {-11, -9, -7, -5, -3}

19. {21, 5, 1, -7, -39}

Step-by-step explanation:

18. f(-2) = -11, f(-1) = -9, f(0) = -7, f(1) = -5, f(2) = -3

∴ range of f = {-11, -9, -7, -5, -3}

19. Range of g = {21,5,1,-7,-39}
