We want to convert the function into the form that let's us easily find the x-intercept, and it would be for the form 
because then we can find the x-intercept in the following manner:
We factor our function 
and get
Now this form let's us easily find the x-intercepts:
and so we pick the second choice: f(x)=(2x+1)(2x-1).
Answer:
x = (-1,-3) y = (5, -1)

Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.
So all you need to do is put the numbers into (x,y) and you'll get (5,2)
Hope this helps!
