Suppose the roots of a polynomial are 4, −7, 8, and 9. Which choice is a factor of the polynomial?

42.4

step-by-step explanation:

convert to decimal

i think the correct option is the second option.

see attached

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

3 qrs + 3/2 xy hope this : /
