1. Use the Intermediate Value Theorem to show that the polynomial function has a zero in the given interval.
f(x) = 13x^4  5x^2 +7x 1; [3,0]
Enter the value of (3).
2. Use the Intermediate Value Theorem to show that the polynomial
function has a zero in the given interval.
f(x) = 2x^3 + 8x^2  7x + 9; [9, 4]
Find the value of (9)

1. since f(0) = 1 and f(3) = 1028, there must be some value 0 < c < 3 where f(c) = 0.
Dunno what you want with 3.
2. since f(9) = 738 and f(4) = 37, there is some 9 < c < 4 where f(c) = 0.
