Which is the polynomial function of lowest degree with rational real coefficients, a leading coefficient of 3 and roots V5 and 2?

f(x) =

Step-by-step explanation:

If    is a root, then so is -

f(x) = 3(x + )(x - )(x - 2)

     =

     = 3()

     =

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
