Use the equation of the poly function f(x) = 2x^3 -x to complete the following.

Question

Use the equation of the poly function f(x) = 2x^3 -x to complete the following. (a) State the degree and the leading coefficient. (b) Describe the end behavior of the graph of the function. (c) Support your answer by graphing the function. The degree of the polynomial is and the leading coefficient is Describe the end behavior of the graph of the function. The curve opens to the right because the leading coefficient is Because the polynomial is he graph has end behaviors in the direction, so the other end opens to the left Which of the following is the correct graph of the function f(x) = 2x^3 -x?

Explanation / Answer

polynomial 3 rd degree

leading coefficient is '2'

x becomes large the function value becomes very large

i.e. limit x tends to infinity f(x) = infinity

graph is 'c' because it is cubic polynomial
