56 + 54
Adding 56 to 2nd number.
1st- exponent
What is the first step?
12(6x - 16)
Multiply 12 by 6x
12*6x = 72x
Which quadrant would this coordinate be in on a graph?

Function Notation
If a c shaped line is plotted on a graph, is it a function.
No. A c shaped line is plotted when there is two outputs(y) for one input(x).
What operation is performed 3rd?
(13 - 3) + 23 - 62
3rd operation is adding first number to 23.
1st- parentheses
2nd exponent
What is the 4th step?
6(3x + 4x - 8)
Add like terms.
1st- 6*3x = 18x
2nd- 6*4x = 24x
3rd- 6*-8 = 48
4th- 18x + 24x
What two quadrants could a negative y value be in?
Quadrant 3 and Quadrant 4
Create a function that represents how much money you can save over time. You receive $50 each week for completing your chores.
f(x) = 50x
x represents the number of weeks.
f(4) = 50*4 =200
In one month (4 weeks), you would earn $200.
Create a function that represents the cost of your manicure of it is $80 to have your nails done and $3 each for any added charms.
f(x) = 80 + 3x
where x represents the number of charms
If you had 2 charms the cost would be:
f(2) = 80 + 3*2 = $86
