Answer:
{-9.5, 1,7}
Step-by-step explanation:
For y =f(x)
domain is list of all values of x and range is list of all values of y
Given
ƒ(x) = 3x – 5
domain = {–1.5, 2, 4}.
thus,
range will be value of f(x)
when x = -1.5
x = 2 and x = 4
Thus,
for x = -1.5
ƒ(x) = 3*-1.5 – 5 = -4.5 - 5 = -9.5
\
for x = 2
ƒ(x) = 3*2– 5 = 6 - 5 = 1
for x = 4
ƒ(x) = 3*4– 5 = 12 - 5 = 7
thus,
range of ƒ(x) = 3x – 5 is {-9.5, 1,7}
