1) Evaluate the limit: lim(x=2) x^4 - 16/x - 2 

2) Evaluate the limit: lim(x=0) [2x^2 - 9x + 5] 

If you could show your work that would be great. Thank you!!

Answer 1

1)

By factoring in to then the limit is

By factoring in to  then the limit is

Now substitute x  = 2 to get the limit

2)

Now substitute x  = 0 to get the limit
