Unit 7 Day 3: Exponential Relations
MBF3CCompare Linear, Quadratic, & Exponential RelationsIn your groups of 3, label yourselves Partner A, Partner B, and Partner C. Each partner completes their respective part of each question.Upon completion of Parts A, B and C, prepare to present your findings to the class.Using desmos, complete a table of values for each:ABCy = 2x - 1y = -1.5xy = 0.75x + 4-2-2-2-1-1-1000111222333Find 1st and 2nd differences for each table of values. Describe any patterns you see.Graph each function:ABC24257001943100045720001943100022860019431000y = 2x - 1 y = -1.5x y = 0.75x + 4Describe the graph:Prepare to explain your findings.Using desmos, complete a table of values for each:ABCy = x2y = 2x2y = -0.5x2-2-2-2-1-1-1000111222333Find 1st and 2nd differences for each table of values.

The top row has 1 can, the second row has 2 cans, the third row has 3 cans, etc. How many cans are there in the 10th row?A soccer ball is kicked. At 1 sec., its height is 20.6m. At 2 sec., its height is 30.4 m. At 3 sec., its height is again at 30.4m. At 4 sec., the height is 20.6m. At 5 sec., the height is 1m.A vase that cost $800 is expected to increase in value by 7% each year for 5 years.Graham got a loan for a car for $16 000. After the first year, he still owed $13 171.37. After the second year, he still owed $10 167.99. After the third year, he still owed $ 6979.37. After the fourth year he still owed $3594.08. After the fifth year, he had paid off his car so there was a zero-balance remaining. Use your formula to find the amount still owing after 6 months (hint: ? or 0.5 of a year)A $600 investment is worth $618 after 1 year, $636 after 2 years, $654 after 3 years and $672 after 4 years. ................
