First we want to find the amount that will be worth 20.7 after one year and 23.81 after two years
So I assume that
Y =p (1.15)^x
Where
Y 20.7
P ?
X 1 year
20.7=p (1.15)^1
Solve for p
P=20.7÷1.15
P=18
The answer is
Y=18 (1.15)^x
The answer is B; the first unit is a position 4 on the x axis, so it goes to the right by 4. -2, in the y axis, would go down. hope this helps!
Yes you have the correct answers for each of the four problems. Nice work.
For anyone curious,
rd = removable discontinuity
id = infinite discontinuity
c = continuous
