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:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
