this is what you want to graph ...f(x) = 32x3 + 12 = 63x2 + 41x

part 1 ...

use your calculator to evaluate ...

f(-1) = ?

f(0) = ?

what does theIntermediate Value Theoremsay about this situation?

part 2 ...

graph the function f(x) in your graphing calculator.

use the root finding capability of the calculator to calculate the value of the function zero that exists between x = -1 and x = 0.
