The price of a television was reduced from $250 to $200. What was the percent of decrease?

20% should be the answer

Step-by-step explanation:

Vertex:

(1,−3)(1,-3)

Focus: (1,−134)(1,-134)

Axis of Symmetry: x=1x=1

Directrix: y=−114y=-114

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.

1−7−41−32−43−7

xy-1-70-41-32-43-7

Graph the parabola using its properties and the selected points.
