What is the equation written in function notation, with x as the independent. To see how this works, take a look at the graph of h(x) = x 2 + 2x – 3. Consider the vertex form of a parabola.

To do this, we simply add a constant term to the function. Hi Mike, y = x 2 - 2 is a quadratic equation of the form y = ax 2 + bx + c, let a = 1, b = 0 and c = -2. A constant function has the form.

The last two easy transformations involve flipping functions upside down (flipping them around the x-axis), and mirroring them in the y-axis. F(x) = f(−x) for all x In other words there is symmetry about the y-axis (like a reflection):. 8 6 g(x) = (x - 3) 3 - 6 4- 6- Use the graphing tool to graph the equation g(x) = 5(x - 3)2 - 1 Use.

In other words, for every x, you would have a unique y. 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). A function defines one variable in terms of another.
