### Examples

The graph of the function can be transformed into the straight line *y*=5*t*+2 by taking the natural logarithm of the function’s outputs.

### Clarifications

*Clarification 1*: Key features are limited to domain; range; intercepts; intervals where the function is increasing, decreasing, positive or negative; constant percent rate of change; end behavior and asymptotes.

*Clarification 2*: Instruction includes representing the domain, range and constraints with inequality notation, interval notation or set-builder notation.

*Clarification 3*: Instruction includes understanding that when the logarithm of the dependent variable is taken and graphed, the exponential function will be transformed into a linear function.

*Clarification 4*: Within the Mathematics for Data and Financial Literacy course, problem types focus on money and business.
