Use The Graph To Find The AOS Vertex Zeros Domain And Range class=

Sagot :

In this problem

we have a vertical parabola open downward

so

the vertex is a maximum

Looking at the graph

The vertex is the point (0,4)

The axis of symmetry is x=0 (y-axis)

The zeros are x=-2 and x=2

The domain is all real numbers -----> interval (-infinity, infinity)

The range is all real numbers less than or equal to 4 ----> interval (-infinity,4]
