Exponential Functions Finding Growth Factor

the exponential function that best fits a set of data

• exponential regression

• exponential decay

• exponential growth

• parabola

Does the table show exponential growth or decay?

• growth

• decay

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

• SLOPE

• RATE OF CHANGE

• STARTING VALUE (y-intercept)

• GROWTH OR DECAY  FACTOR

State if the graph of the exponential function shows growth or decay.

• GROWTH

• DECAY

Identify the y-intercept (initial value) in the function f(x)=13(.27)^x

• (.27)^x
• .27
• 13
• 3.51

Determine whether the sequence is arithmetic, geometric, or neither.

• arithmetic

• geometric

• neither

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

• SLOPE

• RATE OF CHANGE

• STARTING VALUE (y-intercept)

• GROWTH OR DECAY FACTOR

Determine whether each of the following functions is Linear, Exponential, or quadratic.

{(-2, 1), (-1, 3), (0, 9), (1, 27)}

• Linear

• Exponential

• Quadratic

• The number of bacteria increases by 5 bacteria each day

• The number of bacteria increases by t bacteria after 5 days

• The number of bacteria increases by a factor of 5 each day

• The number of bacteria increases by a factor of t each day for 5 days

Which function describes the sequence 1, 3, 9, 27, … ?
