F(x) = -(x2+x-72)
y = -(x - 8)(x + 9)
the solutions are x = 8, -9; so the parabola is upside down (umbrella) crossing the x at 8 and -9, meaning that -9 + 8 = -1/2 = -0.5 is where the focus is, or x = -0.5 as the axis of symmetry
If it was reflected over the x-axis it would become (4,-3).
Answer:
c
Step-by-step explanation:
A = C²/(4π)
A = (56.52 in)²/(4π) ≈ 254.2 in² . . . . the area of the rug
