I need help!!! I’ll mark you brainliest<br> This is timed!!
devlian [24]

Answer:

Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.

( g o f ) = ( 7 x + 1 ) − 1 7  this will result in (gof)=x ( f o g) = 7 x − 1 7 +1 = x − 1 + 1 =x

graphically you can check this if it seems that the functions are reflected over the line x=y.

<u>Answer</u>:

The correct option is C : x² + (y +3)² = 9 .

<u>Step-by-step explanation:</u>

We know that the general equation for a circle is ( x - h )² + ( y -k )²= r², Where,

  • r is the radius.
  • (h , k) is the center.

Let the point be ( 0 , -y) , since it is on negative y axis . And the circle passes through the origin that is (0,0) . Hence the center will be 3 units down the y - axis that is ( 0 , -3) .Hence h will be 0 and y = (-3) .

Now its given that the radius of the circle is 3. So on substituting r = 3 , in standard form we have ,

⇒ ( x -h )² + ( y - k )²= r²

⇒ ( x - 0)² + { y - (-3) }² = 3²

⇒ x² + ( y + 3) ² = 3²

⇒ x² + ( y + 3)² = 9

<h3><u>Hence the correct option is C [ x² + ( y+3)² = 9 ] .</u></h3>
