y=$\frac{5}{12}$

#### Explanation:

I don't really know what you mean by $2e4 x$ since this notation is non standard, I suppose you mean ${2}^{4 x}$.

In this case, you just have to put $x = - 0.5 = - \frac{1}{2}$ in the equation:

$y = \frac{{2}^{4 \left(- \frac{1}{2}\right)} + 1}{3} = \frac{{2}^{- 2} + 1}{3} = \frac{\frac{1}{4} + 1}{3} = \frac{5}{4 \cdot 3} = \frac{5}{12}$

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