Question

Find the range of the function for the fiven domain. f(x)= 3x-8; {-2, -1, 0, 1, 2}

Answer 1

f(x)= 3x-8

x = -2, f(x)= 3(-2) -8 = -6 - 8 = -14
x = -1, f(x)= 3(-1) -8 = -3 - 8 = -11
x = 0, f(x)= 3(0) -8 = 0 - 8 = -8
x = 1, f(x)= 3(1) -8 = 3 - 8 = -5
x = 2, f(x)= 3(2) -8 = 6 - 8 = -2
Domain {-2, -1, 0, 1, 2}
Range: {-14, -11, -8, -5, -2}

answer
Range: {-14, -11, -8, -5, -2}
