FNGR 1 | Lesson 1 | Practice (Identifying Exponential)

Identify each function as linear or exponential and explain why it is either linear or exponential.  Check the function growth at \(x=0, 1\) and \(2\).

1) \(f(x)=3x\)

2) \(f(x)= \left( \Large \frac{2}{3} \right) ^x\)

3) \(f(x)=-4^x\)  and  \(f(x) = 4^x\)?

4) \(f(x)=7(2)^x\)

5) \(f(x)=7(0.5)x\)
