A reader recently asked: I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut the x-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set...
Knowing how to find the vertex of a parabola enables us to write the equation of a parabola given only limited information about it. What is the vertex of a quadratic function? The vertex of a quadratic function is the vertex of the graph of that function. Given a quadratic function in ...
Step 2:Identify the domain and range of the given function. Step 3:The inverse of a quadratic function is a square root function. To graph the inverse, we swap the domain and range. The shape of the graph is the same, only rotated so that it has the doma...
The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter
One way on how to find the vertex and the intercepts of a quadratic function is by graphing. In this method, we can visually see the important points of the graph. However, we can also solve the following algebraically. Answer and Explanation:1 ...

How To: Given a graph of a quadratic function, write the equation of the function in general form. Identify the horizontal shift of the parabola; this value is h. Identify the vertical shift of the parabola; this value is k. Substitute the values of the horizontal ...
Having a quadratic equation to solve, several steps must be followed in order to find its roots (x-intercepts): Rearrange our equation in a form ax2+bx+c=0 Factor it out if possible into a form a(x−x1)(x−x2), then our roots are x1 and x_2 ...
Solution:You can use a number of different solution methods. One is to evaluate the quadratic formula: t= 1, 4 Alternatively, you can factor to find the values ofxthat make the functionhequal to zero. t= 1, 4 You can also graph the function to find the location of roo...
