Question

Find f(5) please explain

Answer 1

-1

Explanation:

A function is represented by the following symbol f(x) where f(x) further represents y like this ,

`y=f(x)`

so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?

We can see in the graph when x = 5 the value of y is -1 to be exact so

f(5) = -1

or

`y=f(x)\\-1 = f(5)\\`
