Answer:
Step-by-step explanation:
Let's just start with the answer. The parent graph is NOT periodic. Graphing a Sine wave or any of the fundamental trig functions gives a period (or repeating function). A periodic function is included below.
The graph of the function does have three roots. They are +/-2 and - 5
0, - 20 is one of the points on the graph.
The problem is A. The parent function does not have to a polynomial. It could just be y = x^3. On the other hand it can be as this one is. I suppose the author of the question is accepting the ambiguity as true.

Answer:
Slope:
y-intercept:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
The slope can be found with the following formula:
In this case you can say that:
Knowing this values you can substitute them into the formula and then evaluate, in order to find the slope. This is:
By definition, the line intersects the y-axis when the value of "x" is 0.
Notice in the table that when ,
Therefore, the y-intercept is:
