Answer the following questions, and explain your reasoning. bring to class an example of a differential equation (or set of equations) describing a physiological or biological system or process. include a reference for where you got the equation (book title, author, and page number if it is from a book; title, author, journal name and volume, and publication date if it is from a journal article; or url if it is from a webpage) as well as a brief description of what the differential equation is meant to model. (make sure to include a description of what the model variables and parameters represent.) we will discuss these examples in class and decide how to classify them: linear or nonlinear? time-invariant or time-varying? causal or noncausal?

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck
