hello
from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.
we can write out an equation in function notation
let the number of hours be represented by x

now we can proceed to solve the cost of the walk for 45 minutes

now we can input the value into the equation and know the cost for 45 minutes walk

from the calculation above, the cost of 45 minutes walk will cost $28.5
 
        
             
        
        
        
-(x+2)^2(x-4)^2
Not that if x= -2 and x=4 they will look like this in an equation: (x+2) and (x-4) 
When (x+2) and (x-4) are set equal to zero and you solve for x, x will equal x= -2 and x=4
If they have double roots, they have a multiplicity of 2 (per root) meaning they will bounce off of the x-axis. Multiplicity can be found by using exponents.
The negative in front flips the function over the x-axis and holds true to the given limit.
