Question

Which of the following graphs represents the function f(x) = x2 + x − 6?

Answer 1

Answer:

Last graph (the parabola)

Step-by-step explanation:

Find the x-intercept and it will tell you which graph is correct. Also the fact that its x^2 should tell you its a parabola and there is only one in the answers.

f(x)=x^2+x-6

=(x+3)(x-2)

x=-3,2

x-intercepts: (-3,0), (2,0)

Answer 2

The answer is: D

Step-by-step explanation:

Direction: Opens Up

Vertex: ( −1/2, −25/4)

Focus: (−1/2, −6)

Axis of Symmetry: x = -12

Directrix:    y = -132
