Best ResponseYou've already chosen the best response.0\(\bf f(x) = \cfrac{x^24x12}{x+2}\to \cfrac{(x6)\cancel{(x+2)}}{\cancel{(x+2)}} \\ \quad \\ \\ \cfrac{x^24x12}{x+2}\qquad {\color{brown}{ x=2}}\implies \cfrac{x^24x12}{{\color{brown}{ 2}}+2}\implies \cfrac{x^24x12}{0}\)

Best ResponseYou've already chosen the best response.0whenever the value of "x", makes the denominator 0, it makes the fraction undefined, and that means that's where the graph has a gap or is discontinued

Best ResponseYou've already chosen the best response.0well, once the x+2 gets cancelled all you're left with is x6 or x6 = 0 x = 6 < solution, or xintercept
