Question

help

Answer 1

help me please find the equation

Answer 2

i plugged in a system and got $Y=-\frac{1}{2}X^3+X^2+\frac{3}{2}X$

Answer 3

y=-1/2x^3+x^2+3/2x

Answer 4

ok, ur ans is correct.

Answer 5

but when i plugged it into my calculator the graph doesn't match the picture...

Answer 6

Answer 8

we have a root at -3, this root looks like of multiplicity 2

so (x+3)^2 is a factor

Answer 9

same with 0 as a root, so x^2 is a factor

Answer 10

we have a root of mult 1 at x = 3, so x-3 is a factor

Answer 11

multiply the factors to get

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

the k is a constant. It's unknown at this point, but it will help force the graph to go through (1,2)

Answer 12

what you do is plug in x = 1 into k*x^2*(x+3)^2*(x-3)

then set that result equal to 2 and solve for k
