Can anyone, with work get me the answer to this problem?

Question

Suppose f(x) = x^2 + 1/x - 1 and g(x) = x + 1/ x^2 - 4. Estimate lim_x->1 f(x) and lim_x->2 g(x)

Answer 1

The functions are and .

To find substitute the value x = 1 in f(x).

.

Therefore, .

To find substitute the value x = 2 in g(x).

.

Therefore, .
