The value of a rare coin increases at a faster and faster rate. Which sketch best represents the situation?
400
2 is paired with 3 and 6, 4 is paired with 7, 5 is paired with 9, and 6 is paired with 11. Function or not a function? Explain
Not a function because 2 (input) is paired two times.
400
determine whether it is a linear or non linear function
x: 4, 8,12,16 y:-9,-25,-41, -57
linear

You are typing at a constant rate. You pause to think about your next paragraph, and then you resume typing at the same constant rate. Which sketch best represents the situation?
500
function or not? why or why not and tell the range and the domain.
Domain: 2, 0, -3 Range: 2, 1, -1, -3
not a function because the input 0 is paired two times

use the graph to write a linear function that relates y to x.
y=1/2x+2

Describe the relationship between the time and the volume of a balloon
as time increases the volume of the balloon increases at a constant rate, then stays constant, then increases at a constant rate, then stays constant, then increases at a constant rate.
