What is the area of the region in the first quadrant enclosed by the graph of y=e^(x^2/4) and the line y=0.5?

When I graphed the two functions they don't even connect so the answer would be infinity. What am I doing wrong>

Integrate y=e^(x^2/4) from x=0 to the point where e^(x^2/4) = 0.5. Call that x-coordinte X.
You may need a table of the error function to do the integration.
Then subtract 0.5 X from the integral. That is the area below the y=0.5 line.
