(12x^2+60x)/(x^2-2x-35)

Question

The graph of this function has a hole in it. What is the x-coordinate of that hole?

(12x^2+60x)/(x^2-2x-35)

johnweldon1993 · Answer

"has a hole in it" means the function is "undefined" at that point

This occurs when the denominator = 0

so what value(s) of 'x' make

x² - 2x - 35 = 0 ??

more clarification about factoring? or more about a function being "undefined" ?

No wait, I got -5

johnweldon1993 · Answer

The weird thing is...your question says this graph has a "hole" it would actually have 2 "holes" because there are 2 values of 'x' that make this function undefined
