Provide an appropriate response.Explain why the domain of the logarithmic function y = log2x does not include negative numbers.
What will be an ideal response?
If y = log2x, then 2y = x. There is no real number y such that 2y equals a negative number.

Evaluate the function for the given values of a and b. Then use the intermediate value theorem to determine which of the statements below is true.a = -2 and b = -1f(x) = 3x5 - 9x3 - 9x2 + 5
A. f(-2 ) and f(-1) have opposite signs, therefore the function f does not have a real zero between -2 and -1. B. f(-2 ) and f(-1) have the same sign, therefore the function f has a real zero between -2 and -1. C. f(-2 ) and f(-1) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between -2 and -1. D. f(-2 ) and f(-1) have opposite signs, therefore the function f has a real zero between -2 and -1.
