The graph of f(x)=4x^3-13x+9x+2 is shown below. How many roots of f(x) are rational numbers?
A. 0
B. 1
C. 2
D. 3

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

p(x)= 8 x³ - 36 x² + 54 x - 27

q(x) = 2 x -3

you can check your mistake and then you can choose the correct option.

dividend =   8 x³ - 36 x² + 54 x - 27

divisor = 2 x -3

if you want to find quotient, proceed as follows

q(x)= 0

2 x - 3=0

x =

now , i have used division method , to find quotient and remainder

the answer is 15 to your question
