Step-by-step explanation:
f(x) = 4x + 5, g(x) = 9x − 4
(f-g)(x) = f(x) -g(x)
=4x+5-9x+4
=-5x+9
=9-5x

Answer:

Step-by-step explanation:
You have the following function:
(1)
In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.
We are given with the following:
Effective annual interest, i = 0.0425
Future worth, F = $25000
Number of years, n = 18
We use the formula to solve for the present worth of the money:
P = F / (1 + i)^n
P = 25000 / (1 + 0.0425)^18
P = 11818.73
The closest answer is:
