    y= sqrt (4-x^2) QUESTION!

    find the area bounded by the curve y= sqrt (4-x^2), the x axis and the y-axis in the first quadrant. I found the x intercepts which are +2 and -2 but we only need -2 and 0 because we are finding it in the first quadrant what's the next steps? please show working out!! :)

    y= -2x^2 -5x+3

    oh true, thanks D94 :)
  15. B

    y= -2x^2 -5x+3

    btw, i got this: 0= -2x^2-5x+3 (-2x-3) and (x+1) therefore x= 1 and x= -2/3 why isn't this right?
