Question

What is the range of y = 5x -2 if the domain is {-3, -1, 0, 1, 3}?
Answer

{-13, -3, 2, 3, 13}

{12, 3, 0, 3, 13}

{-17, -7, -2, 3, 13}

Answer 1

The domain refers to the x values, while the range refers to the y values. So you'll find the range of y = 5x - 2 by substituting in each of the domain instead of x in the equation
ex: y=5*-3-2=-17 and so on.......

U got it ?

Answer 2

noo,

Answer 3

You will substitute every number in the domain set in the equation to get the range :D
Put instead of x the domains number
y=5*-3-2=-17
y=5*-1-2=-7
y=5*0-2=-2
y=5*1-2=3
y=5*3-2=13
Therefore the range ={-17, -7, -2, 3, 13}..
Make sense ?
