Question

F(x)=3 over x+2-x-3 squared what is f(7)

Answer 1

`f(7)=(-5)/(3)` or
`f(7)=-1.67`

Explanation:

We are given the following function of x and we are to find the value of
`f ( 7 )`:

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

Substituting the given value (7) in the above function to get:

`f(x)=(3)/(x+2)-√(x-3)`

`f ( 7 )= \ frac{3}{7+2}-√(7-3)`

`f(7) = \frac { 3 } { 9 } - \sqrt { 4 }`

`f(7)=(1)/(3)-2`

`f(7)=(1)/(3)-(6)/(3)`

`f(7)=(-5)/(3)` or
`f(7)=-1.67`
