You multiply the whole number by the denominator (2x4) then add the numerator (2x4)= 8 then plus 1 so 8+1 is 9 and that's how you get your answer 9/4

Please help!<br> This is mathematics!

Elanso [62]

Answer:

30, 30, 32, 32, 34, 38, 38, 38. Thats how you first need to set it up then what you do is add them all up which would equal to 272. Then you take 272 dived by how many numbers there are (theres 8 numbers) so you do 272/8 which would be 34! So 34 would be your answer.

Find the inverse of the given function.

kodGreya [7K]

For this case we must find the inverse of the following function:

$f (x) = - \frac {1} {2} \sqrt {x + 3}$

We follow the steps below:

Replace f(x) with y:

$y = -\frac {1} {2} \sqrt {x + 3}$

We exchange the variables:

$x = - \frac {1} {2} \sqrt {y + 3}$

We solve for "y":

$- \frac {1} {2} \sqrt {y + 3} = x$

Multiply by -2 on both sides of the equation:

$\sqrt {y + 3} = - 2x$

We raise both sides of the equation to the square to eliminate the radical:

$(\sqrt {y + 3}) ^ 2 = (- 2x) ^ 2\\y + 3 = 4x ^ 2$

We subtract 3 from both sides of the equation:

$y = 4x ^ 2-3$

We change y by f ^ {- 1} (x):

$f ^ {- 1} (x) = 4x ^ 2-3$

Answer: $f ^ {- 1} (x) = 4x ^ 2-3$
