There are infinitely many possible answers. y = x - 4 y = x*0 y = x2 - 16 y = |sqrt(x)| - 2 that's 4 of them.
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7
Usually x (independent) variable is the input and y (dependent variable) is the output.
Where Y = 2x-3, the output for x = 3 is Y = 3. 2x - 3 = 2(3)-3 = 6-3 = 3
Look for a pattern. If it looks like they are changing at the same rate, then y might just equal something plus x, which you can find by taking y-x. If they are changing at different rates, then it may be that y equals something times x, which you can find by taking y/x.
The output depends on what x is. If x = 1, then y = 2.
A function has an input and an ouput. Each input can only have one output. Examples of functions: x = y y = x2 y = cos(x) where y is the output and x is the input.
Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.
the output variable is called the dependent variable. For example the function y = f(x) = 3x here x is independent and y is dependent; y changes when you change x
Y is the output of x, which is the input. So y= x + 2, y is the result of x + 2. Y is the dependent variable, and x is the independent constant.

Y = x - 22 Y = x/3 + 2 Y = 7x/18 sin (pi/2)
Domain (input or 'x' values): -∞ < x < ∞.Range (output or 'y' values): -2 ≤ y ≤ 2.
The range of a function (or equation) is the set of all Y values it reaches. For example, Y = X+2 would reach all real values of Y over the course of all X values. However, Y = X2 would have a range of Y greater than or equal to 0 because no matter what value of X is put in, Y will never be negative. MORE ANSWER...Equations are input and output. Your input value is x, the output value is y. All allowd values of x create an output in y. The x inputs are the "domain values", the y outputs, as a result of x are the "range" values.
If you are talking about 4 mA = 0% and 20 mA = 100% then the formula would be a linear equation: y=mx + b y=6.25(x) - 25 y= percentage x=mA ouput So for example put 4 mA in place of x and you get 0% for y and if you use 20 mA in place of x you get 100% for y. You can rewrite the equation if only Percent input is known to find mA output it would be X= (Y + 25)/6.25 this way you input the percent in for (Y) and you have the mA output for X
The rule you have described is likely a linear function. When the input is -2 and the output is 4, it means that the function relates these two values through a specific mathematical operation. To determine the exact rule, we need more data points or information about the function's form (e.g., y = mx + b for a linear function).
