Question

Find f(-2) if f={(-2,3),(3,0),(0,5),(5,-2)}​

Answer 1

Answer:

$f(-2)=3$

Step-by-step explanation:

Given:

The given function in the set of ordered pairs form is:

$f=\{(-2,3),(3,0),(0,5),(5,-2)\}$

Now, for an ordered pair $(x,y)$, 'x' represents the domain of the function and 'y' represents the range of the function.

$f(-2)$ represents the value 'y' of the function for the given domain value $x=-2$.

So, from the set of ordered pairs given, the ordered pair that has $x=-2$ is (-2, 3).

Here, -2 represents the 'x' value and 3 represents the 'y' value of the function.

Therefore, $f(-2)=3$
