F(1) math

f^{-1}[f[A]] is a set, and x is an element. They cannot be equal. The correct way of proving this is: let x\in A, then f(x)\in \{f(x)\ |\ x\in A\}=f[A] by the definition of image.

What does f^-1(x) mean?

f -1 (x) =. First add 5. Then divide by 3. Not all functions have inverses. A function must be a one-to-one function, meaning that each y -value has a unique x -value paired to it. Basically, the same y -value cannot be used twice. The horizontal

On top of that it then explained how to solve it myself. I was surprised at how helpful this app was! Even when I wasn't sure what I was doing, I could look at what my results are from snapping a pic of my equation and eventually find out the way of which this app went about getting the correct answer.

But the best feature is it's ability to show the steps of the calculation with great detail, most useful app for any student who wants to strengthen his/her understanding of both foundation level and complex maths.

Excellent for double checking my work, best app I ever used This helps me a lot with me in school and I'm glad this was a ad If it wasn't an ad then I would have failed my math class. Very useful for determining the graphs of various functions and many more, it works amazing and it does a lot of things.
