SOLUTION

The correct option is A

Points with coordinates (x,y) on a graph can also be expressed thus:

[tex]f(x)=y[/tex]

So with the above explanation, we can answer the question.

The point (-3,-5) on the graph means that x=-3 and y=-5

So it can be expressed as a function in the form:

[tex]\begin{gathered} f(x)=y \\ x=-3\text{ and y=-5} \\ f(-3)\text{ =-5} \end{gathered}[/tex]

The correct option is A
