How do you graph a function?

To graph a function using this calculator:

  1. Enter your function in the “Function” input field (e.g., x^2)
  2. Use the operation buttons above to insert complex functions
  3. Set your desired X-range (default is -10 to 10)
  4. Click “Plot Function & Generate Table”

How to graph a circle?

To graph a circle with radius r centered at (h,k):

  1. For the upper half: sqrt(r^2 - (x-h)^2) + k
  2. For the lower half: -sqrt(r^2 - (x-h)^2) + k

Example: For a circle with radius 5 centered at (0,0):

  • Upper half: sqrt(25-x^2)
  • Lower half: -sqrt(25-x^2)
