If the domain is {0, 2, -6}, what is the range of y = -2x + 3?

Solution:

Given, domain is {0, 2, -6}

y = -2x + 3

We have to find the range.

When x = 0

y = -2(0) + 3

y = 0 + 3

y = 3

When x = 2

y = -2(2) + 3

y = -4 + 3

y = -1

When x = -6

y = -2(-6) + 3

y = 12 + 3

y = 15

Therefore, the range is {3, -1, 15}.

If the domain is {0, 2, -6}, what is the range of y = -2x + 3?

Summary:

If the domain is {0, 2, -6}, the range of y = -2x + 3 is {3, -1, 15}.
