The scale factor is 4 since 8 divided by 2 is 4
Answer:
1) the factored form is y= ( x-5 ) ( x+4 )
2) the vertex is (4.5, -0.25)
3) the y intercept is when x equals 0 so it is at (0,20)
4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)
5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
Yep you have done it correctly




Divide -20 by 5 to get -4.

Multiply -4 and -3 to get 12.

Multiply 4 and -2 to get -8.

Multiply -8 and -1 to get 8.

Add 12 and 8 to get 20.

Calculate 4 to the power of 2 and get 16.

Subtract 16 from 20 to get 4.
