Elliptical and hyperbolic functions look very similar except for one thing. What is their difference?
Elliptical functions are a sum between x's and y's, hyperbolic functions are a difference between x's and y's.

The cookie store charges you $1.89 for each chocolate chip cookie you plan to buy for your favorite math teacher. You check your wallet and noticed that you only have $33.25. If f(c)=1.89c is a function that models the cost of cookies, or c, what is the appropriate domain notation of this function?
[0,17]

If the center of an ellipse is at (-4, 8) and the major axis is 14 units, what are the vertices?
(3,8) and (-11, 8)

What does DOTS stand for?
Write an example of one that is not on your review or Final exam.
Difference of Two Squares
Not -9, -16, -36, or -144 (if seen already)
200
Why do we have a +- in the quadratic formula?
The +- exists in the quadratic formula because when you find the square root, you can have a positive or negative answer.
Example is sqrt9 can be 3 or -3.

If eccentricity is 1.2, does that create an ellipse, hyperbola, circle, parabola, or neither?
A hyperbola.

When graphing multiple linear functions, sometimes we see parallel and perpendicular lines. How can we tell, other than graphing, when linear functions will be parallel or perpendicular?
Parallel lines have the same slope.
Perpendicular lines have opposite reciprocal slopes.
