Question

Which of the following is a polynomial function? Select all correct answers.

Answer 1

Step 1

A polynomial is an expression consisting of indeterminates and coefficients that involve only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

`\begin{gathered} A\text{ polynomial function is given as } \\ f(x)=a_o+a_1x+a_2x^2+a_3x^3+.\ldots.a_nx^n\text{ for a fixed n}\ge0(\text{ the degr}ee\text{ of f)} \end{gathered}`

Step 2

Find the polynomial function.

Hence, the polynomial functions are;

`\begin{gathered} 1)\text{ f(x) = 3x+5} \\ 2)\text{ f(x) = 4x-5} \end{gathered}`
