To fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and

a. proportions
b. values
c. asymptotes
d. expressions

which fills the blank correctly

C. asymptotes

Step-by-step explanation:

In the figure attached, a sign chart is shown. To fill it out you need to find the function's zeros and asymptotes. The zeros are those x values that makes the function equal to zero, in the example, those are the x values that make the denominator equal to zero (x = -1 and x = 5). In a rational function, the asymptotes are those x values that make the numerator equal to zero (x = -9 in the example)

Function in the example:
