Answer:
[tex]f(1)=-4[/tex]
Step-by-step explanation:
For finding out [tex]f(1)[/tex], we have to find the value of y coordinate of the point where its x coordinate is 1.
From the given graph, the point [tex](1,-4)[/tex] lies on the graph and has x coordinate as 1.
Drawing a vertical line x=1, it meets the graph at [tex](1,-4)[/tex]
Therefore, [tex]f(1)=-4[/tex]
