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) = tan(x) + 2
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) = tan(x) + 2
For the function f(x) = tan(x) + 2, x ≠ π/2 + kπ where k is an integer.
So the function is not defined at x = π/2 + kπ.
Hence the function f(x) = tan(x) + 2 is discontinuous at x = π/2 + kπ.
And, the function f(x) = tan(x) + 2 is continuous for the interval (-∞, ∞) – (π/2 + kx).
The function f(x) = tan(x) + 2 is continuous for the interval (-∞, ∞) – (π/2 + kx
