Fill in the blanks. The graph of a quadratic function is symmetric about its ________.

03:21

In Exercises 17-34, sketch the graph of the quadratic function without using a graphing utility. Identify the vertex, axis of symmetry, and x-intercept(s). $ f(x) = 16 - \frac{1}{4} x^2 $

01:25

In Exercises 7-12, match the quadratic function with its graph. [The graphs are labeled (a), (b), (c), (d), (e), and (f).] $ f(x) = (x + 1)^2 - 2 $

01:44

Fill in the blanks. Linear, constant, and squaring functions are examples of __________ functions.

Okay, So in this video, we are going to be learning about coefficients in matrices. So first of all, just in case people don't know a coefficient is just any number just without a variable, it's just that number. So, for example, if we have two, X two would be the coefficient. If we have two times a matrix, that too would be that coefficient. So basically just a number. So then let's talk about coefficients in terms of matrices. So let's bring that example backup. So let's say that I have this matrix A B C. D. We have the confession to how this would play out is basically just think of it like the distribution poverty, so just, basically, just distribute. What that means is that we want to make sure that this, too, is being multiplied to the A to be to the sea into the D. So the resulting matrix should be to a to B to C and too deep. And that goes for regardless of what kind of a size that matrix has, it's always gonna be The coefficient is going to be distributed to every single item in that matrix. Just be careful because, like if we have really, really big matrix like a B c d e f g h i j k l m N o p Q R. S t. You're doing it by two. You still have to make sure that you're multiplying it by every single number in that matrix. But other than that, it's very simple and straightforward. You just have to use a distributed distribution property.
