how can you find the bounderies given by the curve x=4sqrt(y) and y=4sqrt(x)? show your solution please. thanks to anyone who will notice this!

  1. Steve

    well, um, did you try actually drawing the graphs?

    x=4√y is the right half of a parabola that opens upward

    y=4√x is the upper half of a parabola that opens to the right.

    You can think of it as the area in the 1st quadrant, bounded by

    y=x^2/16 and x=y^2/16

    You have a small lens-shaped region in QI, with vertices at (0,0) and (16,16)


    and review your algebra I!
