The inverse of the function f(x) is x/4 + 3/28
The function is given as:
f(x) = 4x - 3/7
Set f(x) = y
y = 4x - 3/7
Swap the positions of x and y
x = 4y - 3/7
Make y the subject
4y = x + 3/7
Divide by 4
y = x/4 + 3/28
Hence, the inverse of the function f(x) is x/4 + 3/28

Answer:
Step-by-step explanation:
Let x = Total campers
and y = Archery sign up
In a direct proportionality,
y = kx
1. Calculate the value of k
Substitute a pair of values for x and y
150 = k × 45
Divide each side by 45
k = 150/45 = 10/3
2. Calculate the value of x in Week 3
The diagram is a graph of your proportionality. It shows that y = 130 when x = 39.
