B. x2 + x(2a – 5b) – 10ab = 0
C. x2 + x(5b - 2a) – 10ab = 0)
D. x? – x(2a – 5b) + 10ab=0
E. x2 + x(2a - 5b)+10ab = 0

Try D

Step-by-step explanation:

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
