What are the x- and y-intercepts of the graph of y = x2 + x − 6?

Mathematics
1 answer:
fenix001 [56]3 years ago
6 0

Answer:

C

Step-by-step explanation:

To find the y- intercept let x = 0, hence

y = 0 + 0 - 6 = - 6 ⇒ (0, - 6) ← y- intercept

To find the x- intercepts let y = 0, that is

x² + x - 6 = 0 ← in standard form

(x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

Hence x- intercepts are (- 3, 0) and (2, 0)
