2. explain how to find the inverse of f(x) = (x - 1)/4

Inverse = 4/(x-1)

Step-by-step explanation:

When dealing with problems, we are concerned with reversal. This means that an inverse function is a function that reverses another function.

To find the inverse of a function, the numerator and denominator would be reversed.

This means that the numerator will become the denominator and the denominator will become the numerator. Applying this to the question we have,

f(x) = (x - 1)/4

The numerator = (x-1)

The denominator = 4

For inverse of f(x) = (x - 1)/4

Inverse = 4/(x-1)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
