Answer:
25
Step-by-step explanation:
it's so easy to get to know
Step-by-step explanation:
Given
f(x) = 2x - 5
f^-1(x) = ?
we know
Let
y = f(x)
Or y = 2x - 5
Now Interchanging the role of x and y we get
x = 2y - 5
or 2y = x + 5
therefore y = (x+5) / 2
Therefore, f^-1(x) = ( x + 5 ) / 2
Hope it will help :)❤
