But that's wrong. lim of x-> implies that 8 is being approached from both side which would result in two different results, one side resulting in infinity and the other resulting in negative infinity. As it is written, the answer would be "does not exist."
Also, the bottom is wrong because sideways 5 isn't a number.
Not to burst anyones bubble, but it does require small ammounts of math to build a wall out of bricks..theres a certain pattern u must keep for the wall not to simply fallover.
You're confusion is not suprising, ignore the comments below they're wrong as well, when you divide something by increasingly smaller numbers the numbers you start to get get a lot bigger for example if you divide 1/10 you get 0.1 if you divide by 1/1 you get 1 if you divide by 1/0.1 you get 10 if you divide by 1/0.00000000 you start to tend towards an infinityly large number and thats what this means of course it's impossible to divide by zero but as you approach the limits 1/0 tends to infinity
