Question

Y = f(x) = 16x Find f(x) when x = 1/2​

Answer 1

Answer:

The answer depends on what the problem really is.

f(1/2) = 8

or

f(1/2) = 4

See below.

Step-by-step explanation:

This is the problem as it was posted:

y = f(x) = 16x

Let x = 1/2

y = f(1/2) = 16(1/2) = 8

Perhaps the problem is this:

$y = f(x) = 16^x$

If x is an exponent of 16 and not a factor, then the answer is:

$y = f(\frac{1}{2}) = 16^\frac{1}{2} = \sqrt{16} = 4$
