1) Suppose f(x) = −x 2021 − 2x 2020 − x 2019 a) Write f(x) in factored formb) Determine the end behavior of f

c) Find the zeros of f and indicate their multiplicities

d) Sketch a rough graph of f

2) If the work required to stretch a spring 2 ft beyond its natural length

is 12 ft-Ib, how much work is needed to stretch it 6 in. Beyond its natural length?

3) Suppose f is a polynomial function such that f(a) 6= f(b) for a < b

a) Suppose f(a) = −2 and f(b) = 3. Is it true that there exists a number c between a and b such that f(c) = 0?

b) Suppose f(a) = 4 and f(b) = 7. Is it true that there exists a number c between a and b such that f(c) = 0?
