3a + 12 = -9 + 6a
a=7
Evaluate f(x)=-3x if x=2
What is -6?
3x - 7 < 2(x + 4) + 2
x < 17
Find the Domain and Range
Domain: -00 < x < 00
Range: -6 < x < 00
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
Solve for x. y = mx + b
(y-b)/m = x
Evaluate f(x)=2x+1 if x=-2
What is -3?
2x<8 or 3+x>27
x<4 or x>24
Find f(-5)
f(-5) = -4
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
2(x - 12) / 5 = 16
x=52
Solve for x if F(x) = 6
f(x)=-3 - x
x = -9
-3(2n + 1) > 9
n < -2
Find f(6)
f(6) = 3
Is it a function?
| x | y | 
| 2 | 4 | 
| 1 | 5 | 
| 2 | 6 | 
What is NO because x repeats?
4x + 2(x+2) = 5(x-1)
x = -9
Evaluate f(x)=25 + 4x2 if x=5
x=125
16 - (4k - 2) ≥ 2(k + 3)
k < 2
Find the Domain and Range
Domain: -4 < x < 8
Range: -8 < x < 8
Is it a function? 
What is YES because it passes the Vertical Line Test?
Solve for b2
A= ½(b1 + b2)h
2A/h - b1 = b2
Solve for f(x) = 5
f(x)=-59 + 4x2
x=4
-2x+10<4 or 3x-6<12
x>7 or x<6
Find x if f(x) = -2
x = 8 and x = 2.5
Is it a function? 
What is NO because it does not pass the Vertical Line Test?
