Question

Help please!!

Answer 1

The change in water vapor in a cloud is modeled by a polynomial function, C(x). Describe how to find the x-intercepts of C(x) and how to construct a rough graph of C(x) so that the meteorologist can predict when there will be no change in the water vapor. You may create a sample polynomial to be used in your explanations.

Answer 2

to find the x-intercept of any polynomial, set the equation C(x) equal to zero, then solve for x.

Answer 3

How do you solve for x?? @DemolisionWolf

Answer 4

For example,
$$
C(x)=25-0.5x
$$
Where at x=0, C(x)=25 is the initial condition on the amount of water vapor.
Set C(x) = 0:
$$
C(x)=0=25-0.5x\\
0.5x=25\\
x=\cfrac{25}{0.5}
$$
So at this x is when the water vapor will be zero.
