Step-by-step explanation:
(By the way, (x) is f negative one of x, like f(x), but inverse)
f(x) = - 4 is the same as y =
- 4
y = - 4 start with the equation.
x = - 4 switch x and y.
x + 4 = add 4 to both sides.
= y square both sides.
(x) =
change y to the inverse f(x) format.
I hope this helps! :)
An exponential growth model has the form:
we know that the initial population was 3000 and that after seven years the population was 3525, plugging this vales and solving for the unknown we have:
Therefore the missing part of the function is 0.083
