Question

Help! WILL MEDAL! Help! Using the points above as zeros, construct the polynomial function, f(x), that will be the path of your roller coaster. Show all of your work. x= 6, x= -2, x=-7

Answer 1

Answer 2

If the roots are `x= 6, x= -2, x=-7` then the factors are `x-6`, `x+2`, `x+7`


So you need to multiply out `(x-6)*(x+2)*(x+7)`

Answer 3

How would I do that? FOIL?

Answer 4

@jim_thompson5910

Answer 5

the box method is more effective than FOIL

tell me what `(x+2)*(x+7)` is equal to when you use the box method

Answer 6

How do I use the box method?
