What is the Area bounded by x^2 = y, x = 1 , and x - axis?

what does this mean? favor please

thanks

Have you at least graphed those? You should have a parabola (y= x^3), a vertical line (x= 1), and a horizontal line (y= 0, the x-axis). Do you see the region bounded by those? Do you see that you are asked for the area "below" y= x^2 betweeen x= 0 and x= 1? Since you are asking a question like this, I take it you are taking a Calculus class. And you should have learned that the "area below y= f(x), between x= a and x= b" is given by the integral $\int_a^b f(x)dx$. That is the simplest application of the integral and, in fact, is usually used to introduce the integral.

you are only giving things with the same concept of the my math problem but you either cannot answer :)

$\int_0^1 x^2 \, dx = \frac{1}{3}$

The user you are addressing here is a valuable contributor on several forums that I know of personally, and probably several that I do not know of. I have gained insight many times from reading his posts. When you imply that the solution is beyond him, I can but chuckle, yet your demeanor here recently is no laughing matter.

I'm not trying to bust your chops, but please treat the folks here with more respect.

He is giving you the concept needed to answer the question in the hope that you may apply it yourself, and gain an understanding from the application.
