C. f(x)=2/3x-2
<h2>
Explanation:</h2>
Looking at the graph we realize that the y-intercept is given by:

The Slope-intercept form of the equation of a line is given by:

So, our equation becomes:

So the only option that matches a negative y-intercept is C. Let's see that the slope  . Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from
. Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from  to
 to  . In other words:

Answer:D ( if you add +4 to the (x + 3)^2)
Step-by-step explanation:
Parent function is f(x) = x^2
A translation 3 units left gives y = )x + 3)^2
- and 4 up gives y = (x + 3)^2 + 4 - vertex form.
Standard form :
y = x^2 + 6x + 9 + 4
= x^2 + 6x + 13.
 
        
             
        
        
        
Graham: -50x + 14,040
Max:  20x + 12,500
    Graham      =        Max
 -50x + 14,040 = 20x + 12,500
<u>+50x               </u>   <u>+50x               </u>
             14,040 = 70x + 12,500
 <u>          -12,500  </u>  <u>         -12.500 </u>
              1,540  = 70x
               
                 220 = x
Answer: 220 minutes <em>(3 hours 40 minutes)</em>
 
        
                    
             
        
        
        
70-3·6+9
Remember PEMDAS.
You must multiply the 3 and 6 together, and you would get 18. 
Then, you subtract 18 from 70, which would give you 52.
And finally, you would add 9 to 52, getting 61 as your final answer.
