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)
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.
