Question

65pts! plot the vertex and the axis of symmetry of this function:

Answer 1

I can do it but not at now

So.. I will solve this later

Answer 2

f(x)=(x−3)2−5

Find the properties of the given parabola.

Direction:

Vertex: (3,−5)

Focus: (3,−194)

Axis of Symmetry: x=3

Directrix: y=−214

Select a few x

values, and plug them into the equation to find the corresponding y values. The x

values should be selected around the vertex.
