Question

If f(x) = 3/x+2 -sqrt x-3. complete the following statement. Round to the nearest hundredths.

f(7)=___

Answer 1

assuming you mean
`f(x)=(3)/(x+2)-√(x-3)`

subsitute

`f(x)=(3)/(x+2)-√(x-3)`

`f(7)=(3)/(7+2)-√(7-3)`

`f(7)=(3)/(9)-√(4)`

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

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

`f(7)=(-5)/(3)`
f(7)≈1.6666
round
f(7)=1.67

Answer 2

-1.67

Explanation:

We are given that

`f(x)=(3)/(x+2)-√(x-3)`

We have to find the value of f(7).

Substitute x=7

Then, we get

`f(7)=(3)/(7+2)-√(7-3)`

`f(7)=(3)/(9)-\sqrt4`

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

`f(7)=(1-6)/(3)=-(5)/(3)=-1.67`

Hence, f(7)=-1.67
