Answer:
vertex = (- 2, 6)
Step-by-step explanation:
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here a = 5 , thus a horizontal translation left by 5 units.
Thus
vertex of g(x) = (3 - 5, 6 ) = (- 2, 6 )
If you make yourself a monthly expense chart:
Months
<u> 1 2 3 4 5 6 7 8 9 10</u>
Opt 1 -80 -30 -30 -30 -30 -30 -30 -30 -30 -30
Opt 2 -40 -40 -40 -40 -40 -40 -40 -40 -40 -40
By month 5 the total amount spent for Opt 1 is $200 and Opt 2 is $200
For part two add up the values for each all the way up to month 9.
Option 1: 80 + 30(8) = 80 + 240 = 320 spent
Option 2: 40(9) = 360 spent
So option 1 is cheaper by month 9
