Thus, to graph an equation in two variables, we graph the set of ordered pairs that are solutions to the equation For example, we can find some solutions to the firstdegree equation y = x 2 by letting x equal 0, 3, 2, and 3 Then, for x = 0, y=02=2 for x = 0, y = 3 2 = 1 for x = 2, y =
Solve graphically y=x^2 and y=2x-1-Use the graph to find an approximate solution to 3/2 to the x is equal to five So pause this video and try to do this on your own before we work on this together All right, now let's work on this So they already give us a hint of how to solve it They have the graph of y is equal to 3/2 to the x They graph it right over hereHi Mike, y = x 2 2 is a quadratic equation of the form y = ax 2 bx c, let a = 1, b = 0 and c = 2 You can certainly plot the graph by using values of x from 2 to 2 but I want to show you another way I expect that you know the graph of y = x 2 If you compare the functions y = x 2 and y = x 2 2, call them (1) and (2), the difference is that in (2) for each value of x the

First solve for "y" The result is y = / Sqrt 2 x x^2 Note when x = 0, y = 0 When x = 1, y = 1 and 1 and when x = 2, y = 0 For x > 2, y is imaginary and for x < 0, y is imaginary Now calculate y for as many values of x between 0 and 2 as you want to see the graph Ahmad RezaeiY=x2x Geometric figure Straight Line Slope = 00/00 = 1000 xintercept = 0/1 = yintercept = 0/1 = Rearrange Rearrange the equation by subtracting what is y=1x2 https//wwwtigeralgebracom/drill/y=1x2/
