Question

Help!!!!!!!!!!!!!!!
If f(x) = -(24 – 32) – x, find f(-2).

Answer 1

-11

Explanation:

Given :

`f(x) = -(3)/(8) \left(24-(32)/(x)\right) -x`

We have to find f ( - 2 ):

Putting x = - 2 in f ( x ) we get :

`f(-2) = -(3)/(8) \left(24-(32)/(-2)\right) -(-2)\\`

`\implies f(-2) = -(3)/(8) \left(24-( -16)\right) +4 \\`

`\implies f(-2) = -(3)/(8) \left(40\right) +4 \\`

`\implies f(-2) = -3* \left(5\right) +4`

`\implies f(-2) = -15 +4`

`\implies f(-2) = -11`

Therefore value of f ( - 2 ) is - 11.

Answer 2

9514 1404 393

Answer:

-13

Explanation:

Put -2 where x is and do the arithmetic.

`f(x)=-(3)/(8)\left(24-(32)/(x)\right)-x\qquad\text{given}\\\\f(-2)=-(3)/(8)\left(24-(32)/(-2)\right)-(-2)=-(3)/(8)(24+16)+2\\\\f(-2)=-15+2=\boxed{-13}`
