Use the Intermediate Value Theorem to determine whether the polynomial function has a real zero between the given integers.
f(x) = 2x3 + 10x2  8x  5; between 1 and 2
I got: f(1)=1 and f(2)=35;no
Determine the maximum possible number of turning points for the graph of the function.
f(x) = 8x^3  3x^2 + 8x  22
i got 2
f(x) = x^7 + 3x^8
i got 7
g(x) =  1/x + 2
i got 0

I did not get an answer
