Although this function is defined by different formulas in two different cases, it is indeed a continuous function on all of R 2. Well, if X and Y are different values and f(X) = f(Y), then that means that there is a horizontal line which passes through our function at two points (namely X and Y). The last two easy transformations involve flipping functions upside down (flipping them around the x-axis), and mirroring them in the y-axis.

The equation below is not a function because if you isolate x on the left side of the equation, there are two possible values for y, a positive value and a negative value. View Wooksheet.docx from CALCULUS AB at Roy High School. If a<0, it opens downward.

Allow me to jump back on my soap box… This question demonstrates an all too common misunderstanding by math students that is perpetuated by textbooks that ask questions like this one. Quadratic functions are functions in which the 2nd power, or square, is the highest to which the unknown quantity or variable is raised. Y' x 2 + 4 y 3 = 2 - 2x y, and (Equation 1).

Check how easy it is, and learn it for the future. So the solution of the original function pair is x=2, y=0. If we think about the equation (y + 1) 2 = x for a while, we can see that x will be positive for all values of y (since any value squared will be positive) except y = −1 (at which point x = 0).
