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.

Evaluating expressions:<br> 1. x + 9 when x = 3
balu736 [363]

⇨ The numeric value of this expression = 12.

<h3> </h3>
  • To solve this expression, just <u>replace '</u><u>x</u><u>'</u> by the <em>indicated value</em>, being the number 3, and <em>perform</em> the <em>indicated </em>math <em>operations</em>.

{\large \displaystyle \sf {1 \cdot x+9  }}

{\large \displaystyle \sf {x=3  }}

{\large \displaystyle \sf {1 \cdot 3+9  }}

{\large \displaystyle \sf { 3+9  }}

{\orange{\boxed{\boxed{\pink {\large \displaystyle \sf { \ 12 \   }}}}}}\\\\

  • Therefore, we can conclude that, the correct value of this expression = 12.

{\orange{\boxed{\boxed{\pink {\large \displaystyle \sf { \ 12 \   }}}}}}\\\\
