Given:

The graph of quadratic function f is given.

To find:

The y-intercept of the given graph.

Solution:

The intersection of y-axis and the graph of the function is known as the y-intercept of the function.

From the given graph it is clear that the graph of the function intersect the y-axis at 4. So, the y-intercept of the given graph is

[tex]y=4[/tex]

Therefore, the correct option is B.
