Answer:
f(8)=-2
Step-by-step 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
