Which two functions are inverses of each other?
guapka [62]

Answer:

The choices were typed wrong, but we can find the inverse of each option.

For function f(x)=x the inverse is the same function g(x)=x, because an inverse of a function is where their composition gives the independent variable as unique result.

If we do that with each function, we have:

f((g(x))=x; where f(x)=x and g(x)=x, we have

f((g(x))=x\\x=x

So they are inverse.

For f(x)=2x its inverse would be g(x)=\frac{1}{2}x, because

f(g(x))=2(\frac{1}{2}x)=x

For f(x)=4x, its inverse is g(x)=\frac{1}{4}x, because

f(g(x))=4(\frac{1}{4}x)=x

For f(x)=-8x, its inverse is g(x)=-\frac{1}{8}x, because

f(g(x))=-8(-\frac{1}{8}x)=x

There you have all inverses. Basically, if their composition results in x, that means they are inverse.

(2/3x +1 = 5 -8) solve for x no links
sweet [91]
2/3x+1=5-8

Combine like terms:

2/3x+1=-3

Subtract 1 from both sides

2/3x=-4

Multiply 3x from both sides

2=-12x

Now divide -12 from both sides
=-2/12

Simplify and you get -1/6 for your answer
