Inverse function.
\[f(x)=5x+7-2\]\[f ^{-1}(y)\]
@dan815 Can you help?
inverse is b asically
a reverse of functions to arrive at input from output
reverse of operations*
So instead of subtract, addition, and so on..?
ok first simplify ur expression for f(X)
f(x)=5x+7-2 =5x+5
y=5x+5
lets see order of operations
PEMDAS?
you multiply x by 5 then u add by 5
revese to go back
let me give u a simple example to visualize
i told you hey dude! i know all kinds of durty filthy magic I hold in my hand an 1 apple u will duplicate it to get 3 apples then i will add 2 apples to it and give it to you so you have 5 apples iif you want to know how many apples i started with you would be like okay ill take away the 2 apples he added and divide by 3 because he duplicated by 3 so (5-2)/3=1
Okay.
do the same thing to y=5x+5 the last thing we do to x is the first thing we do the opposite of
5*x +5 multiply by 5 and add 5 going back is -5 and divide by 5
y=5x+5 (y-5)/5=x
Oh okay. So (y-5)/5=x is the inverse of f(x)=5x+7-2 ?
