For the following exercises, determine whether or not the given function f is continuous everywhere...f(x) = log2 (x)

For the following exercises, determine whether or not the given function f is continuous everywhere. If it is continuous everywhere it is defined, state for what range it is continuous. If it is discontinuous, state where it is discontinuous.

f(x) = log2 (x)

Solutions

Expert Solution

A function is said to be continuous in an interval if it is defined for every value within that interval.

 

Consider the following function:

f(x) = log2x

 

For the function f(x) = log2x, value of is always greater than 0.

 

So the function is not defined at x ≤ 0.

 

Hence the function f(x) = log2x is discontinuous at (-∞, 0]

 

And, the function f(x) = log2x is continuous at (0, ∞).


So the function is not defined at x ≤ 0.
