The equation that represents a tangent function with a domain of all real numbers such that
is 
<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:

<h3>Undefined function</h3>
This means that, we determine the function that would be undefined when the input value equals

From the list of given functions, only function g(x) is undefined at 
Hence, the tangent function is

Explanation:
This answer is valid because, when you multiply
4
×
1
, you get

The shortest height at which the two stacks of boxes will be the same height is 15.
Hope I was able to help!
x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
