Warm-up Evaluate: 34 4-2 Evaluate each expression for x = 2 x5 5-x

Exponential Function Base and Multiplier Example: f(x) = 2x What were 2 names that we gave the number 2 in this expression? Base and Multiplier

Each year the local country club sponsors a tennis tournament Each year the local country club sponsors a tennis tournament.  Play starts with 128 participants.  During each round, half of the players are eliminated.  How many players remain after 5 rounds?

Exponential Functions

Think about it… Linear, Quadratic or Exponential?

Growth or Decay? When b > 1 , the function f(x) = bx represents exponential growth. When 0 < b < 1, the function f(x) = bx represents exponential decay.

Growth or Decay?

Graphs: Both graphs approach the x-axis but never reaches it…we call the x-axis an asymptote.
