Which equation represents a tangent function with a domain of all Real numbers such that x is not equal to pi over 2 plus pi tim

Rudik [331]

The equation that represents a tangent function with a domain of all real numbers such that $x \ne \frac{\pi}2 + n \pi$ is $g(x) = \tan(n \pi - \frac{\pi}2)$

<h3>Domain</h3>

The domain of a function is the set of input values the function can take

The domain of the function is given as:

$x \ne \frac{\pi}2 + n \pi$

<h3>Undefined function</h3>

This means that, we determine the function that would be undefined when the input value equals

$x = \frac{\pi}2 + n \pi$

From the list of given functions, only function g(x) is undefined at $x = \frac{\pi}2 + n \pi$

Hence, the tangent function is $g(x) = \tan(n \pi - \frac{\pi}2)$

The equation having null set as its solution set is

KIM [24]

Answer:

B) x = e^x

Step-by-step explanation:

The graphs of y = e^x and y = x never intersect, so the solution set will be the empty (null) set for ...

x = e^x

_____

There is one intersection of y=x with cos(x) and with sin(x). There are an infinite number of solutions for x = tan(x).
