Given f(x) = . Homework Help ✎
What is the value of f(–1)?
. Hint: Use polynomial division.
Use what your answer to part (b) to sketch y = f(x) without using a calculator.
If y = f(x) continuous at x = –1? Use the definition of continuity to justify your answer.
What happens when the denominator is 0?
Substitute x = −1 into the quotient.
You know it is a parabola with a hole at x = −1. Find the x-intercepts by factoring.
