How to sketch exponential graphs and reciprocal graphs?

Exponential Functions - Introduction
y = ax, where a > 0
Sketching exponential graphs (using reflections)
y = e-x, y = -ex


 
Sketching exponential graphs (using translations)
y = ex + 2, y = ex - 1, y = ex - 2, y = ex + 1
Sketching exponential graphs (using stretches)
y = e2x, y = ex/2, y = 2ex, y = 1/2 ex
