The students in mr. hardings gym class went on a class ski trip. each student paid $25 and the school paid a total of $300. altogether, the trip cost at most $550. how many students went on the trip? can you right this as an inequality?

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.
