Answer:
f ( - 2 ) =  - 12 
Step-by-step explanation:
f ( - 2 ) = - 3 ( -2 )^2 
then you do the exponent first so 
- 3 ( 4 ) 
now you multpily the - 3 and 4 
you get - 12
 
        
             
        
        
        
Hello,
Answer D
ax-b < -c or ax-b >c
If ax-b >0 then |ax-b| = ax-b ==> ax-b > c
if ax-b <0 then |ax-b|=-(ax-b) > c ==> ax-b <-c
 
        
             
        
        
        
Answer:
Kindly check explanation 
Step-by-step explanation:
Given that:
Cost function of banner advertisement:
C(n) = 0.30n + 5.00
n = average number of hits per hour
5 = flat rate
From the function, C(n), the cost per hit is the slope value of the function ; which is 0.30
1.) If the cost of pop-up advert will double the cost per hit, the cost function for pop-up advert will be :
D(n) = 2(0.30n) + 5
D(n) = 0.60n + 5.00
B.) This change in cost per hit has resulted in change in slope which is defined as :
[Rise / run = vertical change / horizontal change].
Hence, both vertical and horizontal change has occurred.
