Q. Given the function f(x)=x2+21x, then what is f(x)−1 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)=x2+(21)x, and we need to subtract 1 from this function.
Perform Subtraction: Perform the subtraction of 1 from the function f(x).f(x)−1=(x2+(21)x)−1
Simplify Expression: Simplify the expression by combining like terms. f(x)−1=x2+(21)x−1There are no like terms with 1, so the expression is already in its simplest form.
