D.

I think its C

Answer 1

C or A I think..

Answer 2

Have a look at the graph and look along the X-Axis and find -2, then draw an imaginary line straight up and down at x=-2, now look up this imaginary line, and find where the function crosses it, then draw a imaginary horizontal line and see where that crosses the Y axis.

Answer 3

it crosses between 4 and 2

Answer 4

Yeah, it crosses on the line between 4 and 2, which is 3 in this case.

Answer 5

so y = 3 ?

Answer 6

yep

Answer 7

thank you!
