Wrote the following paragraph to prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side:

Check the picture of the proof Gina made.

All the steps are perfectly fine except that the coordinates of D and E are found by the Midpoint formula, not distance formula.

Remark:

The Distance formula is used to find the length of the segment formed between 2 points.

Whereas, the Midpoint formula is used to find the coordinates of the midpoint of a segment formed by 2 points.

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.
