Answer
a - A function is a special relationship where each input has a single output.
b - The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values. The domain is the set of values we plug in to get our range values.
c - The graph of a function is all of the points present on a function placed on a coordinate plane.
d - Independent variable is the variable that we change and dependent variable changes as a result.
