Question

Activity 3: Complete the tables below and graph on the same coordinate plane.

This is my answer in 1 and 2 ♡♡ Hope it's help.​

Answer 1

Answer:

yes it's correct very good

Answer 2

1.) Given

$y=-2x^2$

Domain:

$(-\infty,\infty),\{x|x\in\mathbb{R}\}$

Range:

The range is the set of values that correspond with the domain.

$(-\infty,0],\{y|y\leq0\}$

Graph of the function : Downward Parabola

Vertex: $(0,0)$

Axis of Symmetry: $x=0$

x-intercepts: $(0,0)$

y-intercepts: $(0,0)$

2.) Given

$y=-x^2+4$

Domain:

$(-\infty,\infty),\{x|x\in\mathbb{R}\}$

Range:

The range is the set of values that correspond with the domain.

$(-\infty,4],\{y|y\leq4\}$

Graph of the function : Downward Parabola

Vertex: $(0,4)$

Axis of Symmetry: $x=0$

x-intercepts: $(2,0),~(-2,0)$

y-intercepts: $(0,4)$
