Learning goals: Teacher Facing Explain (in writing) how to see $a$ and $b$ on the graph of an equation of the form $y=a \boldcdot b^x$. Interpret $a$ and $b$ given equations of the form $y=a \boldcdot b^x$ and a context of exponential growth. Write an equation of the form of $y =a \boldcdot b^x$ to represent a quantity $a$ that changes by a growth factor $b$.
