Which of the following statements regarding rates of change of exponential and logarithmic functions is NOT true?
A. The average rate of change is not constant for exponential and logarithmic functions.
B. The methods for finding the instantaneous rate of change at a particular point for logarithmic functions are different than those used
for finding the instantaneous rate of change at a point for a rational
function.
C. The graph of an exponential or logarithmic function can be used to determine when the average rate of change is the least or greatest.
D. None of these

What is the inverse of the exponential function?
A. Linear function
B. Polynomial function
C. Quadratic function
D. Logarithmic function

Which of the following does not describe the use of logarithmic scales?
A. When the range of values vary greatly, using a logarithmic scale with powers of 10 makes comparisons between values more manageable.
B. Scales that measure a wide range of values, such as the pH scale, the Richter scale and decibel scales are logarithmic scales.
C. Logarithmic scales more effectively describe and compare vast or large quantities than they do small or microscopic quantities.
D. To compare concentrations modelled with logarithmic scales, determine the quotient of the values being compared.
