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.
