A) center is (0,0)
Radius = r^2 = 225 => r = 15
b)center is (0,0)
Radius r^2= 178
=> r =13.34
C) center is (0,0)
Radius is r^2 = 49 => r = 7
Hope it helps .
The "standard" parabola with roots 0 and 2 is
All multiples of this parabola, i.e.
have the same roots. We can choose the factor such that the parabola passes through the desided point: if we plug 1, 5 for x, y we have
So, our claim is that the parabola
has roots 0 and 2 and vertex at (1, 5).
You can easily verify this: the roots are guaranteed by the fact that we can write the equation as
The vertex must be at x=1, because it's the midpoint of the roots. Moreover, if we evaluate the function at x=1 we have
as required.
