What is the discontinuity of the function f(x) = the quantity of x squared minus 3 x minus 28, all over x plus 4

Question

mathmale · Answer

Here's my interpretation of what you've presented:$$\frac{ x ^{2}-3x-28 }{ x+4 }=\frac{ (x-7)(x+4) }{ x+4 }$$

mathmale · Answer

Although you can cancel the 2 (x+4) terms, that does not remove the discontinuity you'll have at x=-4.  If you have any questions about this, by all means please ask.

its not right

anonymous · Answer

its f(x)= then u can read it

Explain what you mean, please, by "its not right."

mathmale · Answer

While it's better to label a function like this with f(x)=, as you suggest, that will have no bearing on the answer to this question.

x^2-3x-28 all over x +4
