Question

Use the graph of the quadratic function y = x2 + x + 4 to answer the question.


What are the zeros of the function?

–2 and 4
4 and 0
4 and –4
–8 and –4

Answer 1

The quadratic has no real zeros.
Discriminant: b^2 − 4ac = 1 − 16 = −15 < 0, so y = x^2 + x + 4 does not cross the x-axis (none of the listed choices).
