The function g(x) can be expressed as the inverse of f(x) as;
g(x) = ¼x - 3
<h3>Inverse Functions</h3>
Complete question is;
If g(x) is the inverse of f(x) and f(x) = 4x + 12 what is g(x)?
- Now, for us to find the inverse of a function, we need to make the output the subject of the formula first and then switch the input and new output values.
Thus;
f(x) = 4x + 12
Thus;
(f(x) - 12)/4 = x
x = ¼f(x) - 3
Thus, switching as said above, we now have;
g(x) = ¼x - 3

Explanation:
right ???
At first situation, ratio = x/y = 1/5
5x = y -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5
Substitute the value of y from equation (1),
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5
Originally, There were 5 red marbles in the bag
