Given:
Loaned amount: 450
Payment: 543.75
Term: one month
543.75 - 450 = 93.75 interest for 1 month.
93.75/450 = 0.2083 or 20.83% monthly interest.
0.2083 x 12 months = 2.50 or 250%
The monthly interest rate is 20.83% and its associated APR is 250%.
now, with that template above in mind
f(-2x) will make it f(x) = (-2x)⁴
that means B is -2
