REVIEW QUESTIONS AND
ANSWERS
Instantaneous rate of change - Answer-Is defined as the rate of change at a particular
moment.
y-intercept - Answer-A function's y-intercept can be found by substituting the input
variable with 0.
The output value of a function when the input is 0
asymptote - Answer-When you make predictions in the long run, focus only on the
horizontal asymptote when x is large.
Outliers and coefficient - Answer-Outliers would cause the coefficient of determination
to be smaller (or further away from 1)
possible outliers - interpolation and extrapolationwg - Answer-While both interpolation
and extrapolation values are affected by possible outliers, extrapolation values are more
affected.
Linear functions - Answer-Linear functions have a constant rate of change.
Exponential functions - Answer-it has a constant rate of change and If it is growing by a
percentage it is exponential.
extrapolation moderate model - Answer-You can go out 25% of the model.
Conclusions - Answer-You draw a conclusion based on a regression's correlation
coefficient.
conclusion for correlation coefficient below .70 - Answer-For correlations less than 0.70,
more data or a new approach might be needed.
conclusion for correlation coefficient above .7 - Answer-With 30 data points, a
correlation between 0.7 and 0.9 would justify a strong correlation.
Stretching regression functions - Answer-never stretch the regression function for more
50% of the range without having the training of a regression professional.
