Answer to Question #166972 in Algebra for william

Question

In Desmos, use the sliders to change y= square root of x + k

1. What did the k value do the graph?

Answer 1

ANSWER: GRAPH WILL MOVE UP AND DOWN AS YOU CHANGE THE VALUE OF k.

graph will move up if increase value of K

and will move down if decrease value of K.

EXPLANATION:

Use of desmos

Desmos is a graphic calculator available on web and mobile application which is widely used to solve mathematics equations easily and graphically it provide solution which is helpful in understanding the given problem.

GIVEN EQUATION

$\boxed{y=\sqrt{x} +k}$

USE OF DESMOS FOR GIVEN EQUATION

Put the given equation in equation bar given in desmos (in quadratic with sliders desmos).

and automatically graph of the given equation will appear on the plot area screen.

click on add slider of K.

$\implies$ refer given below figure

$\bigstar$ USE OF SLIDER and solution

after adding slider for K.

use slider to change the value of K

as per equation : as we change the value of K graph will move up and down along y axis

as it shows the value of intercept on y axis.

$\implies$Note: graph will move up if increase value of K

and will move down if decrease value of K.
