Question #a9253

Answer 1

y=`5/12`

Explanation:

I don't really know what you mean by `2e4x` since this notation is non standard, I suppose you mean `2^{4x}`.

In this case, you just have to put `x=-0.5=-1/2` in the equation:

`y=(2^{4(-1/2)}+1)/3={2^{-2}+1}/3=(1/4+1)/3=5/(4*3)=5/12`

Otherwise, let me know, and please use the math environment next time.
