Interval Notation General Rule -- [ and ] includes the number ( and ) do not include the number EX.
-1 < x < 3 = (-1, 3)
4 ways to represent a function
1. 2. 3. 4.
vocab function domain range
Range -- y values Domain -- x values
Name the 3 types of problems in math, where you can't get an answer.
Domain is all real numbers except (these 2 cases) <meta name="qrichtext" content="1" platform="Mac" />< body style="font-size:8pt;font-family:MS Shell Dlg">
5 DIFFERENT CASES YOU WILL SEE: 1. EX.
; Solve for x
0
2. Ex.
; Solve for d
0
3. Ex.
; Solve for d > 0 (d 0, and d 0 )
4. Ex.
; Solve for n 0, and d 0
5. Ex.
; Solve d > 0, and n
0
Increasing and Decreasing Functions **Use the x- coordinates, not y
use the x numbers to tell me the interval, remember brackets or ( )
Odd and Even Functions ** Plug -x into the equation and simplify it: 1. If you get the same answer it is an even f(x) 2. If you get the same answer but a different sign, it is an odd f(x). 3. If you get something different, it is neither odd or even. Ex. f(x) = x5 + x Ex. f(x) = 1 - x4
Ex. 3 f(x) = 2x - x2
Everyday functions **Graph the temperature of water out of the hot water tap, as a function of time
**Graph the height of your lawn as a function of time.
Is it a function or not? *Use vertical line test if line crosses just once, then yes it is if line crosses 2 or more, No it is not
a. State the value of f(-1). b. Estimate the value of f(1.5) c. Estimate the values of x such that f(x) = 1 d. State the domain and range of f. e. For waht values of x is f(x) = .5 f. On what interval is f increasing?
