Exam is tomorow need major algebra help?

Question

let m(x)={(0,1),(1,2),(3,4),(-5,6)}, then the inverse function m^-1(x)

Answer 1

you mean inverse (1,0), (2,1), (4,3), (6,-5) or something else? since an inverse just have the domain and range switched.

Answer 2

If it's using algebra to solve, then using this simple example maybe you will understand?

f(x) = x + 2

First, let f(x) be y.
So,

y = x + 2
Then, let x be the subject meaning you manipulate the equation until it's x = something.

That is:
x = y - 2 in this case.

Then, change the
x into f^-1(x)
and
y into x

and this is the inverse equation already

Meaning, f^-1(x) = x -2

Answer 3

ok(x)=4x+2 might properly be written as y=4x+2 whilst doing inverse purposes you opposite the y and the x words so it would be: x=4y+2 Now take this equation and resolve for y x-2=4y y=(x-2)/4 or a million/4x-a million/2

Answer 4

Bingo to the other responders- Fyi if you graphed the lines the would be each other's reflection

Answer 5

Switch the x and y values.
