Help me please this is really hard?

Step-by-step explanation:

subtitute x values into the equation

Step-by-step explanation:

Well there is no real answer to this, but, replace the numbers, -1, 0 and 1 with the x, for example,

If x is -1, then y is

y=2*-1 + 1 which is -1, so y is -1

y=-1

second, for 0, 2*0+1 is 1, so y is 1

y=1

Third, if x is 1 then y is, y=2*1+1  so y is 3

y=3

so you're 3 y's would be, -1, 1 and 3.

Cheers!
