Question

the point (-3, -5) is on the graph of a function. which equation must be true regarding the function?
○ $f(-3) = -5$
○ $f(-3, -5) = -8$
○ $f(-5) = -3$
○ $f(-5, -3) = -2$

Explanation:

Step1: Recall function point definition

For a function $f(x)$, a point $(a,b)$ on its graph means $f(a)=b$.

Step2: Match given point to rule

Given point $(-3,-5)$, here $a=-3$, $b=-5$. Substitute into the rule: $f(-3)=-5$.

Answer:

A. $f(-3) = -5$
