Find the midpoint of the segment between the points (1,1) and (4,−16).
a. (−5,15)
b. (5,−15)
c. (−3/2,17/2)
d. (5/2,−15/2)

D

Step-by-step explanation:

The midpoint formula is

Filling in our coordinates where they go gives us:

so

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
