measured by using x or y values?

i want to know that relative max or relative min or abs max or abs min, or positive function or negative is measured by using x or y valurs

Did you try to use the textbook and look for answer there?

Did you try to use the internet (e.g. google) and look for answer there?

What did you find?

Before you can look it up, or anyone here can help you, you are going to have to decide exactly what you mean by "measured by x and y values". It's impossible to say what question you are asking.

i just want to know that relative max or relative min we measured by using x or y value
Because in Cartesian coordinate there is two point like (1,2)
1 represent x value and 2 represent y value

You "want to know that the max/min we measured..." is (or does) what? Where is the rest of that sentence?

Many people here do not write perfect English but this is just too difficult to understand.

Perhaps you are asking how we write the max or min value of a function like y= f(x)? Yes, in a Cartesian Coordinate system each point is given by two numbers. If the question is "where" the function has a max or min value, that's "x", the first number in pair. If the question is "what" is that max or min function value, thats "y", the second number in the pair.

Or are you asking about max or min values of a function f(x,y) of two variables? In that case the point (x, y) is "where" the function has max or min values while the value itself is the value of the function, f(x,y).

I want to know that relative maximum, relative minimum value of function is measured by x value or y value?
Like domain is measured in x value and range is measured in y value
Sorry for poor english

The value of relative min or max of a function is the y value. However, it is not incorrect to state the coordinate where the min or max occurs. Either way, it is the y value that speaks to the min or max amount.

"Domain" is a set of x values and "range" is a set of y values while "max" and "min" are specific numbers. As I said above, the actual "maximum" and "minimum" values are values of the function and so y values. The values at which the function takes those values are x values.


For example, the function y= f(x)= 1- x^2 takes on its maximum value (there is no minimum value) at x= 0. That maximum value is y= f(0)= 1.

The function y= f(x)= 2x^3- 9x^2+ 12x+ 6 has a local maximum value at x= 1. That maximum value is y= f(1)= 11. It has a local minimum value at x= 2. That minimum value is y= f(2)= 10.
