Question

How do you find f(8) in (8,-2), (-5,8), (5,3)}

Answer 1

f(8)=-2

Explanation:

Let

x ----> the independent variable or input value

f(x) ---> the dependent variable or output value

we know that

f(8) ----> Is the value of the function f(x) when the value of x is equal to 8

Verify each case

1) (8,-2)

That means

For x=8

The value of the function is equal to -2

so

f(8)=-2

2) (-5,8)

That means

For x=-5

The value of the function is equal to 8

so

f(-5)=8

3) (5,3)

That means

For x=5

The value of the function is equal to 3

so

f(5)=3
