Write an equation that models the following situation:
Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

• y=6(0.14)^x
• y=6(1+14)^x
• y=6(1.14)^x
• y=6(0.86)^x

Is this exponential growth or decay?

• Growth because a=1
• Decay because b=0.5
• Growth because there is no a
• Neither because a=0
