Exponential Functions Assignment

In an exponential function, what does the 'a' represent? 

• SLOPE
• RATE OF CHANGE
• INITIAL AMOUNT
• GROWTH OR DECAY FACTOR

Identify which functions are exponential.

• f(x) = 2x - 5

• g(x) = 3^x

• k(x) = 3x⁴ - 6x + 9

• 
  

  $k\left(x\right)=3\cdot\left(\frac{1}{2}\right)^x$

What is a, the starting term, for the function: f(x) = 300(1.16)^x?

• 300
• 1.16
• .16
• x

Classify the model as Exponential GROWTH or DECAY.
A=1200(.85)⁶
