Student Statement
I am able to express written language algebraically as an exponential equation (in the form y=a*b^x).
I am able to accurately describe the properties of an exponential situation given its equation.
Common Core Standards
SSE.A.1: Interpret expressions that represent a quantity in terms of its context.
CED.A.1: Create equations and inequalities in one variable and use them to solve problems.
CED.A.2: Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
LE.A.1: Distinguish between situations that can be modeled with linear functions and with exponential functions.
LE.A.2: Construct exponential functions given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
LE.B.5: Interpret the parameters in an exponential function in terms of a context.
The following are examples of mistakes that should give you an idea what types of mistakes I am looking for at each level. There are a variety of possible errors while solving problems like this, so this is not an exhaustive list.
As a reminder, here is the scale that is used in class to determine your ability level for each topic:
Below you will find a random situation. Use it to find the equation of the exponential curve. Reveal the answers with the "Check Answers" button. Round all numbers to the nearest thousandth when working through the problem.
