Find the nonpermissible replacement for y in this expression y-9/y+3

y = - 3

Step-by-step explanation:

Providing you mean (y - 9)/(y + 3) then it is always the variable in the denominator that is going to cause trouble. If it equals zero at any point, it's game over.

It's a little better if you get a result like 0/0. That problem has a "depends" as an answer, but by and large, you don't want to monkey around with 0 in the bottom of a fraction.

y + 3 = 0            Subtract 3 from both sides.

y + 3 - 3 = 0 - 3  Combine

y = - 3

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
