JudyOh, dude, the output is technically both X and Y depending on the input, so it's like a choose-your-own-adventure situation. It's like asking if a sandwich is peanut butter or jelly - it's both when you put them together, right? So, yeah, the output can be X or Y, or maybe even Z if you throw in a curveball.

What is the rule if the input x 4 output y 0?
There are infinitely many possible answers. y = x - 4 y = x*0 y = x2 - 16 y = |sqrt(x)| - 2 that's 4 of them.
What function has an output value of 7 for an input value of 4?
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
Is X the input in the line graph?
Usually x (independent) variable is the input and y (dependent variable) is the output.
If a function rule is 2x - 3 what is the output for 3?
Where Y = 2x-3, the output for x = 3 is Y = 3. 2x - 3 = 2(3)-3 = 6-3 = 3
How do you find the function of an input and output table when you are given the values of x and y?
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.
