Hello.

Calculate the area bounded by these curves:

My answer is . I went like this:

For the area above x

and for the area under x

So Someone tell me if the answer is correct cause I don't have the result.

Thanks

the parabola and line intersect at x = 0, and , except at x = 0,

I'm confused. Why you didn't need to separate the area, area above x-axis and area under x-axis(cause under x it will have a -)

it does not make a difference.

if f(x) > g(x), then the area between them is no matter where f and g reside relative to the x-axis.

here is a simple analogy ... consider two points (1, 5) and (1, 2) ... the distance between the two points is 5 - 2, correct?

now, what about (1,5) and (1,-2) ... isn't the distance 5 - (-2) ?

it's the same idea with the functions.
