Answer:
Answer C is correct.
Step-by-step explanation:
f(x) clearly has a maximum:  y = +10 at x = 0.
Analyzing g(x) = -(x + 1)^2 - 10, we see that the vertex is at (-1, -10), and that the graph opens down.  Thus, -10 is the maximum value; it occurs at x = -1.
Answer A is false.  Both functions have max values.
Answer B is false.  One max is y = 10 and the other is y = -10.
Answer C is correct.  The max value of f(x), which is 10, is greater than the max value of g(x), which is -10.
Answer D is false.  See Answer B, above.
 
        
             
        
        
        
Answer:
9
Step-by-step explanation:
y=x
y=kx
substitute k for 0.75 and x for 12 in the above equation
y=0.75×12
y=9
