We have an equation: 80/?= 40/100

Cross multiply:
40*?= 80*100
⇒ ?= 80*100/40= 200

80 is 40% of 200~

0.4a=80 ----- ----- 0.4 0.4 a=200 Where a is the number times 40%, which is 0.4 in decimal form.

Answer:

\frac{ |a + x| }{2}  -  \frac{ |a - x| }{2}  \\  \\  =  \frac{ | - 2 - 6| }{2}  -  \frac{ | - 2 + 6| }{2}  \\  \\  =  \frac{ | - 8| }{2}  -  \frac{ |4| }{2}  \\  \\  =  \frac{8}{2}  -  \frac{4}{2}  \\  \\  = 4 - 2 = 2

Notation

The inverse of the function f is denoted by f -1 (if your browser doesn't support superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse". Although the inverse of a function looks like you're raising the function to the -1 power, it isn't. The inverse of a function does not mean the reciprocal of a function.

Inverses

A function normally tells you what y is if you know what x is. The inverse of a function will tell you what x had to be to get that value of y.

A function f -1 is the inverse of f if

<span><span>for every x in the domain of f, f<span> -1</span>[f(x)] = x, and</span><span>for every x in the domain of f<span> -1</span>, f[f<span> -1</span>(x)] = x</span></span>

The domain of f is the range of f -1 and the range of f is the domain of f<span> -1</span>.

Graph of the Inverse Function

The inverse of a function differs from the function in that all the x-coordinates and y-coordinates have been switched. That is, if (4,6) is a point on the graph of the function, then (6,4) is a point on the graph of the inverse function.

Points on the identity function (y=x) will remain on the identity function when switched. All other points will have their coordinates switched and move locations.

The graph of a function and its inverse are mirror images of each other. They are reflected about the identity function y=x.
