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:
12-3= 9
9^2= 81
Step-by-step explanation:
As the statement indicates that diallo says that the value of 12-3 to the second power is 81, it means that he subtracted 3 from 12 which is equal to 9. Also, the value of 12-3 to the second power means that he calculed the value of 9 squared which is 81.
