Let f(x)= 2x^2+2x-12/ x-3

show tht ƒ(x) HAS A REMOVABLE DISCONTINUITY AT X=2 AND DETERMINE VALUE FOR ƒ(2) would make ƒ(x) continue at x=2

Must define f(2)=???

I tried to plug in 2 for x values after factoring, but the answer i think it was wrong :)

Is the answer 10? I just need a further proof!

$$f(x)\frac{2x^2+2x-12}{x-3}$$This function is continuous at x=2.  Unless I have the function or point wrong.  The function is discontinuous at x=3 though.
