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

Option 1st is correct

`f(-3) = -5`

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`
