Build and analyze an exponential model

Pin the start and the factor; every step follows

10 min 6 stepsGraded practice at the end

Every exponential model runs on two numbers: a start and a factor. The trap is in the step size, and I've walked into enough traps to spot one.

Exponential factor and stepTechniqueMatch the factor to the step it covers
Percent to factor and percent changeTechniqueWrite any percent change as a single factor
Evaluate and invert a functionTechniqueInput given, substitute; output given, solve
Exponent and radical rulesTechniqueRewrite everything as one base to one power
Classify growth as linear or exponentialTechniqueSame difference is linear; same ratio is exponential
