0.0-0.3 Ans✓✓✓ r^2-value showing a weak correlation
0.3-0.7 Ans✓✓✓ r^2-value showing a moderate correlation
0.7-1.0 Ans✓✓✓ r^2-value showing a strong correlation
2 asymptotes Ans✓✓✓ logistic function
always the same Ans✓✓✓ rate of change for a linear function
asymptote Ans✓✓✓ a line that continually approaches a given curve but does
not meet it at any finite distance. A natural limitation
asymptote lower limit Ans✓✓✓ m
asymptote upper limit Ans✓✓✓ L + m
average rate of change Ans✓✓✓ represents how 1 variable changes with respect
to another over an interval of values

, C Ans✓✓✓ start of increase for a logistic equation
C-value Ans✓✓✓ determines how quickly a logistic function starts to grow; the
smaller the value, the quicker it grows
