What polynomial could you add to 3x4 - 9x2 + 5x - x + 7 to get a sum
of 3 + 4x4 + 3x - x + 3x2?

three-fourths of an hour

36÷48=0.75

0.75=

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
