Question

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

Explanation:

Step1: Recall function notation

For a function \( y = f(x) \), a point \((a, b)\) on the graph means \( f(a)=b \).

Step2: Apply to given point

The point is \((-3, -5)\), so \( a = -3 \) and \( b = -5 \). Thus, \( f(-3)=-5 \).
Other options misinterpret the function notation (e.g., using two inputs or swapping input - output).

Answer:

\( f(-3) = -5 \) (the first option)
