Question

3

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

Answer 1

≈ - 1.67

Explanation:

Substitute x = 7 into f(x) , that is

f(7) =
`(3)/(7+2)` -
`√(7-3)`

=
`(3)/(9)` -
`√(4)`

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

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

= -
`(5)/(3)`

≈ - 1.67 ( to the nearest hundredth )
