Consider the function:

h(x)= \frac{x^2-1}{x-1}

As x tends to 1, 

h(1)= \frac{1^2-1}{1-1} = \frac{0}{0}

hence, the y value does not exist.

But

\lim_{x\to1} h(x)= \lim_{x\to1}  \frac{x^2-1}{x-1}  \\  \\ = \lim_{x\to1} \frac{(x-1)(x+1)}{x-1}= \lim_{x\to1} (x+1) \\  \\ =1+1=2

Therefore, the limit of h(x) exists but the y-value does not exist.

Math question down below
Sholpan [36]
5(x + 30) 

x + 30 represents the number of minutes per day he practices
5 is the number of days he practices
so 5(x+30) = the total number of minutes he practices in 5 days

For example, if he practices the piano for 20 minutes per day and the violin for 30 minutes per day, he practices a total of 50 minutes per day. For 5 days that would be 5 x 50 = 250 minutes in 5 days.

Plug that into the equation
5(x+30) = 5(20+30) = 5(50) = 250
