Domain Of A Parabola Graph

If the parabola opens down the vertex represents the highest point on the graph or the maximum value.

Domain of a parabola graph. Determine the domain and range of a parabola. The domain of a graph is the set of x values that a function can take. We can see that the following points are on the graph.

If the parabola opens up the vertex represents the lowest point on the graph or the minimum value of the quadratic function. An alternate approach to finding the vertex is to rewrite the quadratic equation in the form y a x h 2 k. Sometimes you can use a graphing calculator to possess an accurate picture of the function.

The domain of a parabola opening upward or downward consists of all real numbers. 1 1 1 1 2 4 2 4 and so on. In the distance an airplane is taking off.

It is easy to find the domain and range of a parabola when the graph of the same is given unlike when the equation is given. The graph of a quadratic function is a u shaped curve called a parabola. One important feature of the graph is that it has an extreme point called the vertex.

Inspecting the graph will show that y also will take every real value. The domain of a function is the set of all real values of x that will give real values for y. Here x is the independent variable.
