What is the value for f (x) = 3^2x+1 when x = 1/2

Taking 2x is power of 3.

So it will be like 3^ (2*1/2) + 1

You are replacing 'x' with 1/2

and the equation becomes 3^1+1

So, f (1/2) = 4

Answer is 4.

If its like

3^ (2x+1)

Then its like 3^[ (2*1/2) + 1]

It becomes 3^ (1+1) = 3^2 = 9

So, the answer is 9
