The table represents a function ( -4,-2) (-1,5) (3,4) (5,-8) what is f(5)? -8 -1 1 8

-8

Step-by-step explanation:

originally you would be looking at f(x).  

Then you say that x=5 because you are looking for f(5).  

Now, you are given 4 points.  Look for which one has 5 in the x.  Remember (x, y).  

The last one (5, -8) is the one you are looking for because 5 is in the x.  So what you get out after you put 5 in the function is -8 (which is your y).

Note: x is your input and y is your output.  

Another way to look at this is by putting it in a table:

x      y

-4    -2

-1     5

3     4

5    -8

To shorten it, when you plug 5 into x, you will get -8.  

it could be 1,3 and more others to create a cylinder.
