Answer:
<h3>x = 83°</h3>
Step-by-step explanation:

 
        
             
        
        
        
The answer is b. He placed pupp5 to the left of 0
        
             
        
        
        
B. Step 1.  14x - 6 = 9
Step 2.  14x = 15
        
                    
             
        
        
        
The slope of the function is given by its derivative. You want to find the values of x such that the derivative is between -1 and 1.
... f'(x) = 0.4x +5
... -1 < 0.4x +5 < 1 . . . . . your requirement for slope
... -6 < 0.4x < -4 . . . . . . subtract 5
... -15 < x < -10 . . . . . . . multiply by 2.5
Any value of x that is between -15 and -10 will be one where the tangent line has a slope between -1 and 1.
_____
The graph shows tangent lines with slopes of -1 and +1. You can see that the slope of the graph of f(x) is between those values when x is between the tangent points.
