. C.J. has a goal of running 4 miles each Saturday. Last Saturday, C.J. ran 3 miles. He represents the amount of time he was short last Saturday as -1 mile. This Saturday, he wants to make up the difference between his goal and the number of miles that he was short last Saturday. How many miles will C.J. have to run this Saturday?

Answer down below!! :))

Step-by-step explanation:

Since he only ran 3 miles that day, we can say that

Since he wants to run 4 miles, but missed one, that means that he will have to run 5 to make up that one mile, and get his goal!

A. The degree of the function is at least 4

B. At least 3 positive real zeros

Step-by-step explanation:

From the table we can see that the value of the polynomial function is first negative, then positive (1 intersection with x-axis), then again negative (second intersection with x-axis), then again positive (third intersection with x-axis), and at last again negative (fourth intersection with x-axis).

The point of intersection with x-axis corresponds to the zero of the function (f(x)=0). Since the graph of the function intersects 4 times the x-axis, the degree of the polynomial function is at least 4.

the first point of intersection with x-axis has negative x-coordinate. All other points have positive x-coordinates. This means the function has zt least 3 positive real zeros.
