25%
Because You must do the original number by the new.
so, 425-340= 85
but ur not done now,
divide that 85 by the original number then times by 100!
85/340= .25*100= 25%
and ur done hope this helped
Answer:
The inverse function is f(x) = (x + 7)/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x -7
x = 2f(x) - 7
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) - 7
x + 7 = 2f(x)
(x + 7)/2 = f(x)
