A.4.2.2 A Handy Notation
Let’s name the functions that relate the dog’s distance from the post and the time since its owner left: function f for Day 1, function g for Day 2, function h for Day 3. The input of each function is time in seconds, t. Use function notation to complete the table below.
Describe what each expression represents in this context: a. f(15) - read as "f of 15" b. g(48) - read as "g of 48" c. h(t) - read as "h of t"
The equation g(120) = 4 can be interpreted to mean: “On Day 2, 120 seconds after the dog owner left, the dog was 4 feet from the post.” What does each equation mean in this situation? a. h(40) = 4.6 - read as "h of 40 equals 4.6" b. f(t) = 5 - read as "f of t equals 5" c. g(t) = d - read as "g of t equals d"
