Exponential and Logarithmic Word Problems Practice Test
20 applied growth, decay, finance, science, and logarithm questions.
Model real situations with exponential growth, decay, logarithms, interest, half-life, pH, and measurement scales.
20 applied growth, decay, finance, science, and logarithm questions.
Exponential and logarithmic models appear in finance, biology, medicine, physics, chemistry, and environmental science. This test emphasizes choosing the correct model as well as calculating the result.
The questions cover population growth, depreciation, compound and continuous interest, half-life, medication decay, pH, decibels, earthquake magnitude, and doubling models.
You will identify initial values and growth factors, distinguish linear from exponential change, use compound and continuous models, solve for time with logarithms, and interpret base-10 logarithmic scales.
Common errors include using simple change instead of repeated multiplication, entering a percent as a whole number, confusing a half-life with the amount remaining, and reversing logarithm ratios.
