The inverse of a function f(x) is f⁻¹(x) = 4x + 3 after using the concept of the inverse of a function.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
To find the inverse of a function:
Interchange the f(x) and x
f(x) → x
x → f⁻¹(x)
Make the subject f(x);
Thus, the inverse of a function f(x) is f⁻¹(x) = 4x + 3 after using the concept of the inverse of a function.

Width of the miniature model = 
inches
Length of the miniature model = 
inches
The actual width of the boat = 15 feet
Let us find the actual length of the boat.
Write it in a proportion form.
width of model : length of model : : width of actual : length of actual
Do cross multiplication.
⇒ x = 22
Hence the actual length of the boat is 22 feet.
A= 30
Explanation: 88-58=30
Answer:
p = - 5i or p = 5i
Step-by-step explanation:
Noting 
= i
Given
p² = - 25 ( take the square root of both sides )
p = ± 
= ± 
= ± 5i
Thus
p = - 5i or p = 5i
The missing reason is (d) Add the fractions together on the right side of the equation
<h3>How to complete the missing reason?</h3>
From the statements, we have the following equation:
x^2 + b/a x + (b/2a)^2 = -4ac/4a^2 + b^2/4a^2
Next, we add the fractions on the right-hand side of the equation.
This gives
x^2 + b/a x + (b/2a)^2 = [-4ac + b^2]/4a^2
The above means that the last statement is gotten by adding the fractions on the right-hand side of the equation.
Hence, the missing reason is (d) Add the fractions together on the right side of the equation
