f is best modeled by a linear function
Over consecutive equal-length input-value intervals of size___, there is a constant difference in output values of ___.
f is best modeled by a quadratic function
Over consecutive equal-length input-value intervals of size___, there is a second constant difference in output values of ___.
f is best modeled by an exponential function
Input values change additively( in intervals of size ___) as output values change proportionally( by a factor of __).
f is best modeled by a logarithmic function
Input values change proportionally (by a factor of __) as output values change additively (in intervals of size __)
A function f is invertible
Each output value of f is mapped from a unique input value. There are no repeated f(x) values.
The estimated output value found by using a known output and the average rate of change is an overestimate
f is concave down
The estimated output value found by using a known output and the average rate of change is an underestimate
f is concave up
f is positive
The graph of f is above the x/t-axis
f is negative
The graph of f is below the x/t-axis
f is increasing
The graph of f has a positive slope
f is decreasing
The graph of f has a negative slope
The rate of change of f is increasing
f is concave up
The rate of change of f is decreasing
f is concave down
