The equation of parabola is
For point (-1,-9), equation of parabola is
For point (1,7), equation of parabola is
For point (-6,-14), equation of parabola is
So we have three equations , which are
Subtracting first two equation will give
Subtracting second and third equation gives
Substituting 8 for b, we will get
back substituting 8 for b and 1 for a, we will get
So we have
Therefore required equation is
Answer:
I realize its probably not the largest readable font. If you are having trouble reading it, it is the square root of y; however, there is a tiny little 5 in the upper left corner to indicate a fifth root. So you would read it out as "the fifth root of y"
The rule I'm using is
and the more general rule we could use is
where m = 1. This rule helps convert from rational exponent form (aka fractional exponents) to radical form.
