The number of customers, N, in a store t hours after midnight is given by the
function:
N(t)= -t^2 + 28t - 171
How many customers will be in the store at 4pm? --------CORRECT ANSWER
- N(t)= -t^2 + 28t - 171


-(16^2) + (28 x 16) - 171




*Note: work the exponent, but the number needs to be negative for the equation
to work. The negative does not square.


Function Notation ------- CORRECT ANSWER -F(x)
F: Output (x): Input


F(a)= b
F and b: Output




C(state)= Capital
Example: C(Utah)= Salt Lake City

,(input, Output)

Example: (Utah, Salt Lake City)




On a graph, the input will be the horizontal X axis On a graph, the output will
be the vertical Y axis


Rate of Change -------- CORRECT ANSWER -y2-y1


x2-x1




Independent vs. Dependent -------- CORRECT ANSWER -The cause is the
independent variable (the time on a bike = independent)
The Dependent variable is the effect (Calories burnt depends on how much time
spent on the bike = dependent)


C(m) C(50)=450
C= calories burnt-output (50)= time on the bike-input
450= total calories burnt-output




What is a variable? ------- CORRECT ANSWER -In math, things that change
are called variables, and they are often used in equations. And to be clear, when
something is called a variable, it means that it either changes frequently or
changes from person to person. Variables are usually represented by a letter, like
t for time, n for number, c for color, or r for revenue. Letters just make variables
easier to work with.
