gamenerd123 · Answer

So how can I be sure that its 3?

mathstudent55 · Answer

Look at my example above.
What is the value of function f(x) when x = 3.
Look up x = 3.
|dw:1480951539514:dw|

mathstudent55 · Answer

Now see what is the y-coordinate of point in the function that has x = 3.
|dw:1480951584621:dw|
