−7


−5


−1

Answer 1

I’m not sure how to read the expression. Two common interpretations:

1) y = √(12x + 3) − 9
For x = 13: y = √(159) − 9 ≈ 12.609 − 9 ≈ 3.609 (none of the choices).

2) y = √(12x + 3 − 9) = √(12x − 6)
For x = 13: y = √150 ≈ 12.247 (none of the choices).

Could you confirm the exact function (for example, is it y = √(12x+3) − 9, or y = 12√(x+3) − 9, or something else)? Then I’ll compute the correct y-value.
