Question

Some day help me with this 2 question?

Answer 1

Answer:

As x approaches 0, f(x)=2

Step-by-step explanation:

First plug in f(x) and f(0) into the limit.

$\lim_{x \to 0\0} 2x^2+1-(2(0^2)+1)/x^2$, simplify things a bit

$\lim_{x \to \ 0} 2x^2/x^2$,   divide by x^2

$\lim_{x \to \ 0} 2/1=2$, as x approaches 0, f(x)=2
