Question

If f(x) =(if necessary)?(x-76what is the value of f(3), to the nearest thousandth

Answer 1

The function we have is:

`f(x)=\frac{\sqrt[]{x}-7}{6}`

And we need to find the value of f(3).

To solve this problem and find f(x), we need to substitute x=3 into the given function.

• Substituting x=3 into f(x) to find f(3):

`f(3)=\frac{\sqrt[]{3}-7}{6}`

And now, we start solving the operations.

Since the square root of 3 is equal to 1.732:

`f(3)=(1.732-7)/(6)`

Substracting 7:

`f(3)=(-5.268)/(6)`

And finally, dividing by 6:

`f(3)=-0.878`

To round to the nearest thousandth we need to round to 3 decimal places, which in this case we already have, thus, the final answer is:

`-0.878`
