A particular type of cell doubles in number every hour. Which function can be used to find the number of cells present at the end of h hours if there are initially 4 of these cells?

• n= 4(1/2)^h

• n= 4(2)^h

• n= 4+ (2)^h

• n= 4 + (1/2)^h

What type of function is this: y = a(b)^x

• Linear

• Quadratic

• Exponential

• Rational

State whether the equation represents exponential growth, exponential decay,

or neither.

f (x) = 5 • 0.3^x

• Exponential growth since b > 1

• neither

• Exponential Decay since 0< b<1.

An exponential function is graphed on the grid.

• g(x) = 6(1/3)^x

• g(x) = 6(3)^x

• g(x) = 6 − (1/3)^x

• g(x) = 6 − (3)^x
