Q. Given the function f(x)=−31+21x3, then what is f(x)+2 as a simplified polynomial?Answer:
Write Function and Operation: Write down the given function and the operation to be performed.We are given the function f(x)=−(31)+(21)x3 and we need to add 2 to this function.
Add 2 to Function: Add 2 to the function f(x).To add 2 to f(x), we simply add 2 to the constant term of the function.f(x)+2=(−(31)+(21)x3)+2
Simplify Constant Terms: Simplify the constant terms. Combine the constant terms −31 and 2. −31+2=2−31=36−31=35
Write Simplified Polynomial: Write the simplified polynomial.Now that we have simplified the constant terms, we can write the simplified polynomial.f(x)+2=35+21x3
