Answer 2

To find the value of the function $f(x) = \frac{2x}{3+x}$ when $x = 0$, we can substitute $x = 0$ into the function and calculate the result.

Let's substitute $x = 0$ into the function:

$f(0) = \frac{2(0)}{3+0}$

Simplifying further:

$f(0) = \frac{0}{3}$

Since any number divided by 0 is undefined, we cannot evaluate the function at $x = 0$ using this formula. However, we can explore the behavior of the function as $x$ approaches 0 from both the positive and negative sides.

As $x$ approaches 0 from the positive side (i.e., $x \to 0^+$):

$f(x) = \frac{2x}{3+x} \to \frac{2(0^+)}{3+0^+} = \frac{0}{3^+} = 0$

As $x$ approaches 0 from the negative side (i.e., $x \to 0^-$):

$f(x) = \frac{2x}{3+x} \to \frac{2(0^-)}{3+0^-} = \frac{0}{3^-} = 0$

Therefore, the function $f(x) = \frac{2x}{3+x}$ approaches 0 as $x$ approaches 0, but it is undefined at $x = 0$ since the denominator becomes 0.
