if $6700 is invested at 4.6% interest compounded semiannually, how much will the investment be worth in 15 years???
2 answers:
The correct equation to use is as follows:
where A is the amount after t years, P is the principal, r is the annual interest rate expressed as a decimal and n is the number of times the interest is compounded in a year.
Plugging in the given values we get:
After 15 years the investment will be worth $13,253.90

Answer: a)
Step-by-step explanation:
Since we have given that
a.) Find the inverse of f(x) and name it g(x).
Let f(x) = y
So, it becomes
Switching x to y , we get
b) . Use composition to show that f(x) and g(x) are inverses of each other.
Similarly,
so, both are inverses of each other.
c) Draw the graphs of f(x) and g(x) on the same coordinate plane.
As shown below in the graph , Since for inverse function we need an axis of symmetry i.e. y=x
And both f(x) and g(x) are symmetry to y=x.
∴ f(x) and g(x) are inverses of each other.
