Question

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

a) 0,7,29
b)0,7,15
c)3,-1,-9
d)3,-1,15

Answer 1

d) 3, -1, 15

Explanation:

Put the values of x to the equation y = -2x + 3:

for x = 0:

y = -2(0) + 3 = 0 + 3 = 3

for x = 2:

y = -2(2) + 3 = -4 + 3 = -1

for x = -6:

y = -2(-6) + 3 = 12 + 3 = 15
