If you can help at all on even one, that would be much greatly appreciated! Need by tomorrow thanks!
Inverse functions:
A. f(x)=5(x-2)
B. g(x)=2(x+1)^2-3
Solve this system algerbraically:
y=(x+2)^2-1
y=2x+6
Solve this system algerbraically:
12=2*abs(3-2x-x^2)=4
Exponential growth and decay:
Sumari invested $13,500 i an account that accrues 8% annual interest compounded weekly.
a. Write a function to represent this situation.
b. Determine how uch money Sumari will have after 10 years. (assuming no withdrawals are made)

A. f(x)=5(x-2) This function's inverse is 1/5x-10
B. g(x)=2(x+1)^2-3 - assuming 2-3 is -1, the inverse would just be 2(x+1).
Use equal values for this system. 2x+6=x+2. x=-4, y=-2. (-4, -2)
a.y=13500(1.08)^x
b.substitue 10 for x, you get about 29145.5.
