Question

Y=f(x)=3x

value of f(1/2)

Answer 1

You just need to substitute x with 1/2

Your answer will then be 3(1/2) which is 3/2 or 1.5

Answer 2

For this case we have a function of the form
`y = f (x).` Where:

`f (x) = 3^x`

We must find the value of the function when
`x = \frac {1} {2}`

So, we have:

`f (\frac {1} {2}) = 3 ^ {\frac {1} {2}}`

By definition we have to:

`\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}`

Then, rewriting the expression:

`\sqrt {3} = 1.73`

Answer:

`3 ^ {\frac {1} {2}} = 1.73`
