Question

3

If f(x) = - -√x-3, complete the following statement (round your answer
x+2
to the nearest hundredth):
f(7) =___

Answer 1

The answer to your problem is, - 1.67

Explanation:

To evaluate f(7) substitute x = 7 into the expression

f(7) =
`(3)/(7+2) - √(7-3)`

`= (3)/(9) - √(4)`

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

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

= -
`(5)/(3)`

Which is around - 1.67

Thus the answer to your problem is, - 1.67
