Please help out. Thank you.
A right triangle has one leg on the x-axis. The vertex at the right end of that leg is at the point (3,0). The other vertex touches the graph os y=e^x. the entire triangle is to lie in the first quadrant. Find the maximum area of this triangle.Justify your answer.
A=(3-x)(e^x)/2 <-- is this the right equation?

Yes it is the right equation. Good job!

is the max. area 3.6945?

Yes, that's correct too.
In exams and in general, if the number is a "round" number like e⊃2/2, I would give the answer as e²/2=3.6945(approx.)
because the latter is an approximation. This will give the exact value as the answer.
