Question

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3.

Answer 1

First of all, f(x) is basically your y coordinate for a particular x coordinate or value of x. So you can write y=4(x+3)-5.

Answer 2

f=4(x-3)-5
f+5=4*(x-3)
(f+5)/4=x-3
(f+5)/4 +3 = x
now interchange x anh f
(x+5)/4 +3 = f this is ur inverse function

Answer 3

inverse=(x+5)/4 +3

Answer 4

Just as gorv did, you basically interchange x and y or write x in terms of y. That, will be your inverse function. Remember inverse always interchanges the x and y. Now, you just plug in the value of x to get the required answer.

Answer 5

@silversurfer ...your approch is also right i forgot to look at that ...as i ws in hurry lolll

Answer 6

do you know the answer?
