Question 893236: Help Please. do not understand question.....Use the intermediate value theorem to determine whether the polynomial function has a zero in the given interval.
f(x) = 9x^4 - 10x^3- 3x - 9; [-1, 0]
Answers given:
f(-1) = 13 and f(0) = -9; yes
f(-1) = -13 and f(0) = 9; yes
f(-1) = -13 and f(0) = -9; no
f(-1) = 13 and f(0) = 9; no

Find the value of the function at the two endpoints.
Since the value of the function was positive 13 and then became negative 9, somewhere between x=-1 and x=0, the function had the value of zero.
