Answer 1

well, the form of a normal parabola is
y= ax^2 +bx+c

however, the parabola given is a reflection off of y=x

hence the form of the parabola would look something like

x=y^2+by+c

and like the normal parabola, c is the y-intercept or in this case, the x-intercept

substitute hte two values in and you can determine a and b
