Question

part of the graph of the function f(x) = (x + 4)(x − 6) is shown below. which statements about the function are true? select two options. the vertex of the function is at (1,−25). the vertex of the function is 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.

Explanation:

Answer:

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