1) The
vertex equation of the quadratic function has the form:
y = A(x - h)² + kWhere h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.
The coefficient A may be found when you have another point of the quadratic function.
2) Therefore, being the vertex (0,0),
h = 0 and k = 0, and the equation is
y = Ax²3) Replacing the coordinates of the
point (-2,2) into the equation you get:
2 = A (-2)² ⇒ A = 2/4 = 1/24) The resulting equation is
y = (1/2)x² ← answerSince, the system is giving me an error, I had to put the second part of the answer in a separate file. Please,
see the attached pdf file.
16/21 = 0.7619 so the answer would be 0.76
If the decimal can't be written into a ratio, then it is not rational.
