(1, -10) EDIT: Überschrift und Funktionsgleichung korrigiert zu: y=(x-2)^2-1 . y=2x-13 Geometric figure: Straight Line Slope = 4.000/2.000 = 2.000 x-intercept = 13/2 = 6.50000 y-intercept = -13/1 = -13.00000 Rearrange: Rearrange the equation by subtracting what ... More Items Share ( x - 2 )2 - 1 = 0 All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. x = + 3 y = -5 x=\frac{-1±\sqrt{1+\left(-4y\right)y}}{2y}. Divide \frac{1}{y}, the coefficient of the x term, by 2 to get \frac{1}{2y}. Der Scheitelpunkt ist S(2/-1). Multiply both sides of the equation by x^{2}+1. Subtract y from both sides. Der Scheitelpunkt ist S(2/-1). ", Willkommen bei der Mathelounge! y=2x-10 Geometric figure: Straight Line Slope = 4.000/2.000 = 2.000 x-intercept = 10/2 = 5 y-intercept = -10/1 = -10.00000 Rearrange: Rearrange the equation by subtracting what is to ... https://socratic.org/questions/what-is-y-and-x-when-y-2x-11-and-y-x-8.

Extended Keyboard; Upload; Examples; Random; Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. | x - 2 | = 1 x = 1 Stell deine Frage EDIT: Habe oben die Funktionsgleichung entsprechend deinem Kommentar geändert. x+\frac{1}{2y}=\frac{\sqrt{1-4y^{2}}}{2|y|} x+\frac{1}{2y}=-\frac{\sqrt{1-4y^{2}}}{2|y|}, x=\frac{\sqrt{1-4y^{2}}}{2|y|}-\frac{1}{2y} x=-\frac{\sqrt{1-4y^{2}}}{2|y|}-\frac{1}{2y}. Explanation: Solve your math problems using our free math solver with step-by-step solutions. This step makes the left hand side of the equation a perfect square. y = 2x - 12 can be graphed by ... https://www.tiger-algebra.com/drill/y=2x-13/. Subtract \frac{1}{2y} from both sides of the equation.
This equation is in standard form: ax^{2}+bx+c=0. x = 3, "Schon die Mathematik lehrt uns, dass man Nullen nicht übersehen darf. Factor x^{2}+\frac{1}{y}x+\frac{1}{4y^{2}}.
Meinst Du die Funktion One way to solve the problem is to subtract the two equations from each other. Add -1 to \sqrt{1-4y^{2}}. Blue line: Von hier aus um 1 nach rechts (oder links) und um 1 nach oben führt zu den Nullstellen x1=1 uns x2=3. You can use desmos.com to graph these for free and then you just click on the point of intersection, but if you had to do it by hand... ( x - 2 )2 = 1 Take the square root of both sides of the equation. Use the distributive property to multiply, https://math.stackexchange.com/questions/2361415/show-that-y-frac2xx2-1-lies-between-1-and-1-inclusive, Your second and third approaches are workable, but they lack the part proving that the fraction otherwise is between, https://math.stackexchange.com/questions/2367735/explain-why-the-graph-of-y-frac4xx21-and-y-2-sin2-arctan-x-are-the, https://socratic.org/questions/what-is-the-domain-and-range-of-y-x-x-2-1, https://math.stackexchange.com/questions/1333602/is-there-a-horizontal-asymptote-in-y-frac-xx2-1, Horizontal asymptotes for the graph of a function, https://socratic.org/questions/how-do-you-find-the-critical-numbers-for-y-x-x-2-25-to-determine-the-maximum-and, Andrea S.
