Does the graph x-y2 equals 1 represent x as a function of y?
X - Y^2 = 1 - Y^2 = - X + 1 Y^2 = X - 1 Y = (+/-) sqrt(X - 1) now, X is represented as a function of Y. Function values are generally Y values.
What is a polynomial function?
A polynomial function of a variable, x, is a function whose terms consist of constant coefficients and non-negative integer powers of x. The general form is p(x) = a0 + a1*x + a2*x^2 + a3*x^3 + ... + an*x^n where a0, a1, ... , an are constants.
How do you write 6x plus 2y equals 24 as a function?
Generally, function values are Y values, so.......... 6X + 2Y = 24 subtract 6X from each side 2Y = - 6X + 24 divide both the integers on the right by 2 Y = - 3X + 12 -------------------------the function
Is 1 -2 a function?
1-2 is not a function because there is no defined function, such as f(n)=0n+1-2. Also, it does not contain a variable.
What is the lower bound of the function x4 - 2?
You obtain the absolute minimum of the function when x=0. (0^4)-2 =0-2=-2. So, the lower bound of the function is -2.
