Question 1

Find the x-intercepts.
-f(x) = 3x + x(x - 5)
A) (0, 0) and (2, 0)
B) (-2, 0)
C) (0, 0) and (-2, 0)
D) (2, 0)

Accepted Answer

The x-intercepts occur where f(x) = 0. Setting 3x + x(x - 5) = 0, we get x(3 + x - 5) = 0, which simplifies to x(x - 2) = 0. Thus, x = 0 and x = 2 are the x-intercepts.
