Find the Domain and Range
Domain: -00 < x < 00
Range: -6 < x < 00
100
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
200
Solve for x. y = mx + b
(y-b)/m = x
200
Evaluate f(x)=2x+1 if x=-2
What is -3?
200
2x<8 or 3+x>27
x<4 or x>24
200
Find f(-5)
f(-5) = -4
200
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function?
What is False, the points fail the vertical line test
300
2(x - 12) / 5 = 16
x=52
300
Solve for x if F(x) = 6
f(x)=-3 - x
x = -9
300
-3(2n + 1) > 9
n < -2
300
Find f(6)
f(6) = 3
300
Is it a function?
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is NO because x repeats?
400
4x + 2(x+2) = 5(x-1)
x = -9

x=125
400
16 - (4k - 2) ≥ 2(k + 3)
k < 2
400
Find the Domain and Range
Domain: -4 < x < 8
Range: -8 < x < 8
400
Is it a function?
What is YES because it passes the Vertical Line Test?
500

f(x)=-59 + 4x2
x=4
500
-2x+10<4 or 3x-6<12
x>7 or x<6
500
Find x if f(x) = -2
x = 8 and x = 2.5
500
Is it a function? 
What is NO because it does not pass the Vertical Line Test?
