Calculate the following limits using the various techniques we have learned. Show all steps. 1. For the following functions, list the x-values that make f undefined. Then, pick a number VERY close to that x-value from the left, THEN FROM THE RIGHT, within 0.01 of the x-value that makes f unde- fined, and plug it into the function to determine if the function ap- proaches plus or minus infinity or if it approaches a particular number. f(x)= 3
x−2
2. f(x) = (x+1)(x+2) (x+1)
