Answer:
Step-by-step explanation:
Essentially, begin by flipping the x and y terms:
x = (1 - 2y)^2 + 5
Then, solve for y:
Because we know there is only 1 y-value for any given x-value, the inverse of the given function is also a function.
Every 5800 years, your element will decrease by 50%. So one way to represent that as an equation is:
f(t) = (1/2)^(t/5800)
So if t = 5800 years, our equation will be (1/2)^1 or 1/2 or 50%, so it checks out.
