Question #2e63a

Answer 1

Referring to the same frame, the second `y = x^2` graph is the parabola with vertex at O, axis along y-axis and focus at `(0, 1/4)`. The 1st `y=x^2-3` graph is this brought down, by 3 units,

Explanation:

Referring to the same frame of axes, for both the graphs, the second

`y = x^2` graph is the parabola with vertex at O, axis along y-axis

and focus at `(0, 1/4)`. The graph for the first parabola `y=x^2-3` is

obtained by moving the second down, by 3 units,

The parabolas are of the same size `a = 1/4`. They are coaxial,

along y-axis, upwards..

The vertex of the first `y+3= x^2` is at `(0, -3)` and its focus is at
`(0, -11/4)`.
