Answer:

f(x) = ( x + 1 ) ( x - 8 )

Step-by-step explanation:

We have to find a polynomial equation that has double zeros at x = - 1 and at x = 8

Therefore, the polynomial has only two roots and it will be a quadratic polynomial and it has factors ( x + 1 ) and ( x - 8 )

So, the polynomial is y = f(x) = ( x + 1 ) ( x - 8 ) (Answer)

Can someone help me with this

AleksAgata [21]

Check the picture below.

now, looking at the picture's scaling, from the lower-left-corner up to 20 is 5 squares, the rectangles you see in the picture are 40 units each, namely 10 squares. Every square is 4 units, it goes up 12 squares, namely 48 units, and goes to the right by 30 squares plus 4 more, 34 squares, that's 136 units.

well, if we were to make a triangle for the slope, check the picture, it'd look like that.

Why is the slope negative? well, because is going down from left to right.
