To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.
Original equation:
y = 4x + 5
Switched:
x = 4y + 5
Solve for y by isolating it:
x - 5 = 4y + 5 - 5
x - 5 = 4y
(x - 5)/4 = 4y/4

Let the cost of the hair dryer equal x.
The net cost plus a 40% markup equals 42, set up an equation and solve forex.
1.4x = 42
Divide both sides by 1.4
X = 42 / 1.4
X = 30
The net cost was £30

Answer:
Differentiation is concerned with things like speeds and accelerations, slopes and curves ect. These are Rates of Change, they are things that are defined locally. The Fundamental Theorem of Calculus is that Integration and Differentiation are the inverse of each other.
