Simply substitute the value of 
3
 given. In other words, 
f
(
3
)
 is the function of 
f
(
x
)
, however, in this case, 
x
 is 
3
f
(
3
)
=
3
(
3
)
−
4
Distribute 
3
 through the parenthesis
f
(
3
)
=
9
−
4
Simplify
f
(
3
)
=
5
 
        
             
        
        
        
Answer:
The answer is C) - |x - 2| + 3 = 0
Step-by-step explanation:
a) - |x - 2| + 3 > 0
The greater than means something above the graph.
b) - |x - 2| + 3 < 0
The less than means something below the graph.
c) - |x - 2| + 3 = 0
The zero doesn't do anything.
y = - a |x - h| + k = 0
(h,k) is the origin.
h is shift left/right, h = 2 so shift right 2.
k is shift up/down, k = 3 so shift up 3.
The a, affects the y-values which cause the graph to reflect across the x-axis.
 
        
             
        
        
        
8000-4.989 so when you see the word less than it means that you have to subtract and more than you have to add so the answer for this question will be 7,995.011
