4th degree, so the ends both point in same direction
positive leading coefient so both ends point up
factor it to see wheere the roots are
the roots are r1,r2,r3,r4 in P(x)=(x-r1)(x-r2)(x-r3)(x-r4)
factor
P(x)=(x-3)(x-2)(x+1)(x+3)
the roots are
3,2,-1,-3
disregard negative roots becasue you can't have negative time or something
3 or 2

Answer:
Slope of the line
Step-by-step explanation:
Given that,
The point lies on the curve
.
If is the point lies on
.
To find:- Find the slope of line .
So,
The coordinates of point when it lies on
if then
So, ≡
and many points can be calculated by given Equation.
Using the formula when two points .
Then, substituting the coordinates we get,
⇒
Therefore,
Slope of the line
