Y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.
Answer:
coordinates of H = (1, 0)
Coordinates of G = ( - 3.6, -2) or (5.6, -2)
Step-by-step explanation:
E(5,3) and F (2,-1) are two vertices of a square EFGH and H is in the x-axis.
Let the coordinates of H is (x, 0) and G is (a, b).
The length of side EF is
So,
And
Now
Solving (1) and (2)
b = - 2 ,
