These two problems have been bugging me for a while now. on problem 1, you have to use limit laws, not by using numbers near 7. the answer is -1/16.
on problem 2, i just couldnt figure it out, but i do understand the greatest integer function to a certain extent, i even used a calculator that had it on there. thanks in advance.
1.Evaluate the limit if it exists:
lim (square root of(x+2) - 3) divided by x-7
x approaches 7
2. This one uses the greatest integer function:
if f(x) = {x} + - {x} show that lim x approaches 2 f(x) exists but is not equal to f(2).
