I've heard people say its the area UNDER a curve...

but then how would you even get a definit answer surely it may be infinite if theres no restrictions?

Thanks

For a definite integral from a to b, you would be calculating the area of a region bounded as follows:

On the left by the vertical line defined by x=a

On the right by the vertical line defined by x=b

On the bottom by the horizontal line defined by y=0

On the top by the graph of the function.

Note that if the curve is below the x axis then this area is counted with a minus sign

But yes, other than this concern about the sign of the result, it is calculating the area above the graph and below the x axis.
