How does the Function Calculator work?

Takes various functions (exponential, logarithmic, signum (sign), polynomial, linear with constant of proportionality, constant, absolute value), and classifies them, builds ordered pairs, and finds the y-intercept and x-intercept and domain and range if they exist.
This calculator has 1 input.

What 5 formulas are used for the Function Calculator?

  1. The y-intercept is found when x is set to 0
  2. The x-intercept is found when y is set to 0
  3. The domain represents all values of x that you can enter
  4. The range is all the possible values of y or ƒ(x) that can exist
