If f(x) is discontinuous, determine the reason.
inn [45]
The function is 

f(x) = \begin{cases} x^2-4 &\mbox{if } x\ \textless \ 1, \\ 
x+4 & \mbox{if } x\ \textgreater \ 1. \end{cases}.

To the left of 1 the function is a quadratic polynomial, to the right, it is a linear polynomial. Polynomial functions are always continuous, so the only candidate point for discontinuity is x=1.

The left limit is calculated with 1 substituted in x^2+4, which gives 5.

The right limit, is computed using the rule for the right part of 1, that is x+4. 

Thus, the right limit is 1+4=5.

So, both left and right limits are equal. Now if f(1) is 5, then the function is continuous at 1.

But the function is not defined for x=1, that is x=1 is not in the domain of the function. Thus, we have a "whole" (a discontinuity) in the graph of the function.

The reason is now clear:

Answer:<span> f(1) is not defined</span>

The perimeter of a bedroom door is 26 feet. The door is 4 feet wide. How tall is it?
Elden [556K]
If the perimeter is 26, and the width is 4, then add 4 twice, to get 8. Then subtract 8 from 26 to then get 18, you have two lengths, so divide 18 by 2. Your answer is 9.

To check add  4+4+9+9 = 26.

hope it helped! :)
