use the graph of the following function f(x) to find f(0)

Explanation:

Step1: Recall function - value meaning

$f(0)$ is the $y$ - value when $x = 0$.

Step2: Locate $x = 0$ on graph

On the $x$ - axis, find $x=0$. The graph intersects the $y$ - axis at this point.

Step3: Read the $y$ - value

The line intersects the $y$ - axis at $y = 1$.

Answer:

$1$
