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

substitute 0, 2, and -6 in for x in the equation y = -2x + 3

If you start with you 0 you get,

y = -2(0) + 3
y = 0 + 3
y = 3
So 3 is in the range. Can you do the rest?

Answer 2

Oh! Just substitute the domains for x. Easy! Thanks!! Answer is D. :)
