Question

Graph the function. Clearly show 5 points on the graph. List the vertex, axis of symmetry, and domain and range in interval notation.

f(x)=-x2

Answer 1

x y

0 0

1 -1

-1 -1

2 -4

-2 -4

a = 1 b=0 c = 0

axis of symmetry is x=1

vertex (0,0)

domain is all reals

range is (-infinity, 0]
