Question: Defining Function

Write a Maple command to define the function f that is given by

f(x)=x^5+2*x^3+3 .

In the box below, enter the part of your Maple command that is to the right of the ":=".

(Do not include the semi-colon (";") at the end.)

 

The answer I typed in is x^5 + 2*x^3 + 3 but it is wrong. Can someone help me what am I missing.
