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.
1
The graph is negative on the entire interval
4

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

5. The graph is negative on the entire interval -4 < x < 6.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
