What is y when x is three?
In mathematics, when we have an equation with two variables like y = f(x), we can find the value of y when x is three by substituting x = 3 into the equation. Without the specific equation provided, it is impossible to determine the value of y when x is three. The solution would depend on the function or relationship between y and x given in the equation.
How can you determine if an ordered pair is a solution to an equation?
plug the x coordinate in the x part of the equation and plug the y coordinate in the y's part of the equation and solve
What is a function that is equal to twice its derivative?
Assuming function of one variable... Want y[x] s.t. y''[x] =y[x] The characteristic equation is r^2 = 1. r = (+/-) 1 So, e^(x*1) and e^(x * -1) work. To get full generality, multiply them by any constants A,B and add. y[x] = A e^x + B e ^(-x) y'[x] = A e^x - B e ^(-x) y''[x] = A e^x + B e ^(-x) = y[x]
What is the standard form of the equation y equals -x plus 1?
X-y=1
What is the equation to 2 units down of the graph of y equals x?
y=x-2
