Answer:
1 zero: Answer C
Step-by-step explanation:
Keep in mind that the polynomial value is zero at any root. Therefore each point that is a root must lie precisely on the x-axis (where y = 0). In the graph given there is only one such point (Answer C)
1) To solve for x, is to leave the x on the left side the other variables on the right along with the constants, like this

Note that, we subtracted 5 and then divided by x.
