Question

mary creates a table of values for a function and plots the points. she finds that the difference in the y values is the same. what kind of function did she graph?
linear
quadratic
square root
exponential

Explanation:

A linear function has a constant rate of change, meaning when the input (x-values) increases by a consistent amount, the output (y-values) changes by the same constant difference. Quadratic functions have a constant second difference in y-values, square root and exponential functions have non-constant first differences in y-values.

Answer:

linear
