While the domain is easy to determine figuring out the range of a parabola may take you a little bit longer. Find the domain of 1 e 1 x 1 function domain. Domain of log x x 2 1 x 2 1 domain.

Because the parabola is open upward range is all the real values greater than or equal to 0 25. Square root of cos x. So find the vertex and use its y coordinate its x coordinate is b 2a calculate that and plug it in for x to get y.

Range is everything from the y coordinate of the vertex up if a is positive or down if a is negative. This article explains step by step how to find the domain and range of a parabola with any orientation. It s a key skill you need.

If it has the form y ax 2 bx c domain is all numbers. Parabolas are commonly graphed figures in algebra and calculus. Here are some examples illustrating how to ask for the domain and range.
