Can someone help me with these questions.

C ( x = 2 (multiplicity of 2), x = -2, x = -4)

A ( x = 5 (crosses), x = -3 (touches))

Step-by-step explanation:

Here are a couple of rules that helped me come to these answers.

1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.

2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.

3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.
