Question

Compare and contrast the two quadratic equations below. In order to receive full credit, use complete sentences to describe the following:

The direction each parabola opens
The vertex of each parabola
y = x2 − 2x
y = −2x2 + 4x − 3

nurali · Answer

The direction the first on is upwards, as the coefficient of x is positive, for second, goes downwards, as coefficient is negative. The first equations vertex is (1,-1), the second is (1,5)
