The Quadratic Formula

Question 3 • LVA- Mathematical Modeling - Fall

The solutions to a quadratic equation are x = 2 or x = -3. What are the x-intercepts of the related quadratic function?

Answer
A
-2 and 3
B
2 and -3
C
2 only
D
-6 and 6

Explanation

The x-intercepts occur where the quadratic function equals zero, so their x-values are the solutions to the quadratic equation. Since the solutions are x = 2 and x = -3, the x-intercepts are 2 and -3. This matches choice B, “2 and -3.”
