And you are able to pick that out just by looking at the quadratic in vertex form. Now let's get a few more examples under our belt so that we can really get good at picking out the vertex when a quadratic is …

Now, there's many ways to find a vertex. Probably the easiest, there's a formula for it. And we talk about where that comes from in multiple videos, where the vertex of a parabola or the x-coordinate of the …

Factoring out a variable does not help us obtain the quadratic's vertex form; it only helps us find the roots of the quadratic function. To make it easier to obtain vertex form, you are allowed to factor out …

Once you've graphed the vertex, move 1 unit to the left and right of the vertex to get two new "x" values to find more points to complete your graph. For each new value of "x", you use it in the equation and …

We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world problems.

In vertex form, you have an expression with x squared, and then you're multiplying by negative five right over here. This tells us that it's gonna be downward-opening.

So, you graph the vertex and then find points to the left and right of the vertex. When Y is isolated already and the equation is in vertex form, it is easier to pick values of X and calculate Y especially …

What is vertex form? Vertex form is another way of writing a quadratic equation. It looks like this: f (x) = a (x h) 2 + k , where a , h , and k are constants. The vertex form is particularly useful for graphing …

Sal finds the zeros, the vertex, & the line of symmetry of quadratic functions given in vertex form, factored form, & standard form.

Sal rewrites a quadratic equation in vertex form and shows how it reveals the vertex of the corresponding parabola. Created by Sal Khan and Monterey Institute for Technology and Education.
