Hello I am trying to explain why the function h(x)
$h(x)= x^{99} + x$
will always have the area without determining an antiderivative of h(x) that we must have
First I thought of drawing the graph and noticed that the area under the curve on the right side will be identical to the area above the curve on the left side.
I am not sure how to explain in detail why the area bounded by b,-b will always equal to 0.
