SOLUTION: Use the intermediate value theorem to determine whether the polynomial function has a zero in the given interval. f(x) = -2x^4 + 2x^2 + 4; [-2, -1] a. f(-2) = 20 and f(-1)

Question 1061308: Use the intermediate value theorem to determine whether the polynomial function has a zero in the given interval.
f(x) = -2x^4 + 2x^2 + 4; [-2, -1]
a. f(-2) = 20 and f(-1) = 5; no
b. f(-2) = -20 and f(-1) = 4; yes
c. f(-2) = 20 and f(-1) = -4; yes
d. f(-2) = -20 and f(-1) = -4; no
