Question

HELP!! Given rhe polynomual function below find f(3)

Answer 1

34

Explanation:

You substitute 3 in for x, so your equation is now 2(3)^3 - 7(3) + 1.

You solve using P.E.M.D.A.S.

Start with 3^3 (3*3*3) = 27 Now the equation is 2(27) - 7(3) + 1.

-7(3)= -21 and 2(27)= 54.

Now it's 54 - 21 + 1.

54 - 21 is 33, add 1.

34.

Hope this helps!
