Question

Part of the graph of the function f(x) = (x + 4)(x - 6) is shown below. which statement about the function are true? Select two options. - The vertex of the function is at (1,-25) - The Vertex of the function as at (1,-24) - The graph is increasing only on the interval-4< x < 6. - The graph is positive only on one interval, where x < -4. - the Graph is negative on the entire interval -4 < x < 6.

Answer 1

The vertex of the function is at (1,–25).

The graph is increasing only on the interval −4< x < 6.

Explanation:

A and C on edg

Answer 2

Hya, The vertex of the function is at (1,-25) and the Graph is negative on the entire interval -4 < x < 6.

Explanation:

1. the vertex of the function:

f(x)= (x + 4)(x - 6) = x^2 - 2x - 24

x₀= 2/2= 1 y₀= 1^2 - 2*1 - 24= -25

(1; -25)

2. the Graph is negative on the entire interval -4 < x < 6
