x = 13
−7
2
−5
−1

Answer 1

I can’t reliably read the function from the text you pasted — it looks garbled. Could you retype it using parentheses and a clear radical, for example:

y = -√((1/2)x + 3) or y = -(1/2)√(x + 3) etc.?

If the intended function is y = -√((1/2)x + 3), then at x = 13:
y = -√(0.5·13 + 3) = -√(9.5) ≈ -3.082 (none of the choices you listed).

If you post the correctly formatted function I’ll compute the exact y-value and pick the correct choice.
