15x^3+4x^2+14x+12
Multiply 3x by every value in the second bracket. Then multiply 2 by every value in the second bracket. Add like terms. (Only answers with the same square are like terms.)

Determine the inverse function

Replace f(x) with y

Swap the positions of x and y

Multiply both sides by -2


Square both sides


Make y the subject

The inverse has been solved. So, we need to replace y with f'(x)

Next, is to determine the interval

Change inequality to 

Hence, the inverse function is:

<h3>
Answer: Choice (a)  $1,653.66</h3>
=====================================================
Work Shown:
Use the compound interest formula
A = P*(1+r/n)^(n*t)
A = 10000(1+0.039/1)^(1*4)
A = 11,653.65589441
A = 11,653.66
That's the amount of money Tammy will have at the end of 4 years. 
Subtract off the principal from this value to get the interest.
interest = A - P
interest = 11,653.66 - 10,000
interest = 1,653.66
