Evaluate x/4+3y^2 for x =8 and y = 3.

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?

|y + 2| > 6 {y|y < -8 or y > 4} {y|y < -6 or y > 6} {y|y < -4 or y > 4}
