determine the range of each relation for the domain {-3,-2,-1,0,1,2,3}
a) y=-3x+4
b)y=2x^2+5
c)y=1/x-4
d) y=-5(x+1)^2-4

• Math -

To find the range, substitute the values from the domain.

Example: y = -3x + 4

y = -3(-3) + 4 = 9 + 4 = 13
y = -3(-2) + 4 = 6 + 4 = 10

So, we are finding the range of 13 and 10 s0 far
