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

Answer 1

$f(-3) = -5$

Answer 2

Answer:

Option 1st is correct

$f(-3) = -5$

Step-by-step explanation:

If any point $(x, y)$ is on the graph then we can write the function as:

$y= f(x)$

where

x is the independent variable and

y is the dependent variable.

As per the statement:

The point (–3, –5) is on the graph of a function.

⇒x = -3 and y = -5

By above definition we have;

$f(-3) = -5$

Therefore, the equation must be true regarding the function is, $f(-3) = -5$
