X = -3y + 2
-3y = x - 2
f^-1(x) = y = -(x-2)/3
The inverse here is just a straight line so it is a function.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Decrease rate (d)= 7%
Number of periods (n)= 7 years
Current population (PV)= 48,000
<u>First, to calculate the future value, we need to use the following decrease exponential formula:</u>
<u />
FV= PV*[(1+d)^-n]
<u>After 7 years:</u>
FV= 48,000*(1.07^-7)
FV= 29,892
Answer: x = 6
Step-by-step explanation:
Substitute the first y= equation into the y of the second. Distribute as needed and solve for x. x=2 and then plug it in to find y. y=7
Answer:
y=x^2+7
Step-by-step explanation:
Distribute the 2nd power to the x and the 2
you will get x squared +4+3
simplify equation
y=x^2+7
that is your answer
