y=2,-2,-4,-4,-2,2,8

y=x^2+x-4

When x=-3

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

= 2

When x=-2

y=(-2)^2+(-2)-4

=-2

when y=-1

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

=-4

When y=0

y=0^2+0-4

=-4

When x=1

y=1^2+1-4

=-2

When x=2

y=2^2+2-4

=2

when x=3

y=3^2+3-4

=8

dunno

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
