At a sushi restaurant, each sushi costs $5 and drinks cost $2 each. You begin with a drink and 1 sushi.
Write a function that demonstrates the relationship between number of sushi and cost of your meal.
C(s)=5s + 2
f(g(2))
g(x)=x+2 f(x)=3x
f(g(2))=12
What is the difference between solving for f(x) when given x and solving for x when given f(x)?
One is giving you the variable and asking for the functions total value.
The other is giving you the functions total value and asking you to solve for the variable that gave that total.

You and 4 friends agreed to meet at the movies. To save time, the first friend to arrive offered to buy everyone's ticket snacks and be reimbursed later.
The total cost was $100. How much does each person owe you?
20
f(g(-2))
f(x)=x+5 g(x)= -3x
f(g(-2))= -9
Solve for f(x) given x=3
f(x)=2x-5
f(x)=1
What are the first four terms of this Explicit Equation? t(n) = 4n + 1

At Honey Beepot, the bulk price for honey is $2.50 per pound, with a minimum purchase of 20 pounds. If Bobby paid $80 for some honey, by how many pounds did Bobby's purchase exceed the minimum?
12
f(g(1/2))
f(x)=1/4 + x g(x)=(1/2)x
f(g(1/2))=1/2
Solve for x when given f(x)=13
f(x) = 2x + 9
13 = 2x+9
x = 2
At a craft fair, Tony bought 3 items, Isabella bought 1 item, and Tanisha bought 5 times as many items as Tony and Isabella did combined. Which of the following represents the number of items Tanisha bought?
(3+1)*5
f(g(-3))
f(x) = -2x2 g(x) = 3x+4
f(g(x))=-50
Solve for f(x) when given x=5
f(x) = 3x + 6(x-2)
f(x) = 33
What is the second term of this Recursive Sequence? t(1) = 2; t(n) = t(n-1) + 2

Tina has tracked her quiz scores and noted that each hour of studying added 15% (*1.15) to her weekly quiz grade.
Her first quiz grade was 62%. What do you predict her next quiz score will be if she studies 4 hours that week?
94%
f(g(3))
f(x)= 5x g(x) = (1/3)x
f(g(x)) = 5
Solve for x when given f(x)= 34
f(x)=2x2+2
x = 4
34=2*x2+2
What are the first four terms of this Recursive Sequence? t(1) = 0; t(n) = t(n-1) - 4
0, -4, -8, -12
