Answer:
<h3>What are inverse functions?</h3>
Inverse functions undo the operation of the original function. That is, if x undergoes function f to become f(x), then the inverse function (denoted by f⁻¹) reverse what function f does. Thus, the inverse function of f changes f(x) back into x.
<h3>Obtaining the expression for inverse functions</h3>
The inverse of a function can be found in 3 main steps, which is to first let y= f(x), then make x the subject of formula before replacing x with f⁻¹(x) and y with x.
Let's apply the above steps to solve the question!
Given: f(x)= 8x +7
Step 1: Let y= f(x).
y= 8x +7
Step 2: Make x the subject of formula.
<em>Start by subtracting 7 from both sides:</em>
8x= y -7
<em>Divide both sides by 8:</em>
Step 3: Replace x with f⁻¹(x) and y with x.
