Which of the following are the x-intercepts on the graph of the function
shown below?
f(x) = 2(x+1)(x - 2)

Respuesta :

Answer:

x = - 1 and x = 2

Step-by-step explanation:

Given

f(x) = 2(x + 1)(x - 2)

To find the x- intercepts let f(x) = 0, that is

2(x + 1)(x - 2) = 0

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x - 2 = 0 ⇒ x = 2
