Unit 3 Day 3

Warm-Up Write a Function rule for each of the following. 1, 1, 2, 3, 5, 8, ... 1, 10, 100, 1000, ... The cone and sphere have equal volumes. Find the radius of the sphere.

HW Check A) x = 1 b) x = -10 c)x =5 d) X = -3 A) 5 b) 1 C) 4 d)8 A) Start =3 Next = Now +4 6th= 23 B) Start = 1 Next = Now*3 6th = 32 C) Start = 5 Next = Now + 3 6th = 20

On the lined side of the index card: Create a sequence that can be represented by a now/next function. Give at least 4 terms in your sequence. Write your name on the lined side of the index card.

Find a partner NOT at your table. Write the partners name on the white side of the index card. Have your partner create the now/next function for your sequence. Partners turn in the index card to the bin at the front of the room.

Terms: Input is a value that is entered Output a value that is calculated from the input value using a set rule explicit equation an equation that tells how to calculate an output value based on a given input value (** Does not depend on the previous term – Recursive equations do**)

Notation f(x) = x + 4 f(x) = Reads as “f of x” X = input values f(x) = output values once you have solve the function rule

Generate a table of input/output values for the function rule:

Given the input/output values, find the function rule!
