Exponential Vs Logarithm

What is the domain and range of the function y=2^x ?

Use the graph to help!

• Domain: All Real Numbers

  Range: y>0

• Domain: $\left(-\infty,\infty\right)$
  Range: $\left(1,\infty\right)$

• Domain: −2<x<∞

  Range: y>0

• Domain: $\left(-\infty,\infty\right)$
  Range: $\left(0,\infty\right)$
