Question

The function g(x) = x2 – 10x + 24 is graphed on a coordinate plane. Where will the function cross the x-axis?

(–6, 0) and (–4, 0)
(–2, 0) and (–12, 0)
(4, 0) and (6, 0)
(12, 0) and (2, 0)

Answer 1

g(x) = x^2 − 10x + 24 = (x − 4)(x − 6), so the roots are x = 4 and x = 6.

The function crosses the x-axis at (4, 0) and (6, 0).
