Let ƒ(x) = (x^{2} - x - 42) / x-7
find as x → 7.
Now I approach x from both sides and it get me 2 different answer.
So which one is correct:
13 or 14?
Please post your working.View attachment 102575 I was doin' some coursera quiz. It asked this question :

The function is not ##f(x) = \frac{x^2-x-42}{x} -7##, as you wrote.View attachment 102575 I was doin' some coursera quiz. It asked this question :

Yes it must be like ƒ(x) = (x2 - x - 42) / (x-7).The function is not ##f(x) = \frac{x^2-x-42}{x} -7##, as you wrote.
