Understanding Quadratic Functions and Y-Intercepts

Emerson compares two quadratic functions, one represented as a table and the other as a graph. The focus is on identifying the Y-intercepts of these functions. The Y-intercept is where the graph touches the Y-axis or where x equals zero in a table. For the graph, the Y-intercept is at (0, -3), and for the table, it is at (0, 3).

What are the two representations of quadratic functions that Emerson is comparing?

• A table and a graph

• An equation and a list

• A graph and an equation

• A table and a list

What is the y-intercept of a function?

• Where the graph is at its lowest point

• Where the graph touches the x-axis

• Where the graph is at its highest point

• Where the graph touches the y-axis

What is the y-intercept of the quadratic function represented by the graph?

• 3, 0

• -3, 0

• 0, -3

• 0, 3

Where do you find the y-intercept in a table representation of a function?

• Where x equals 0

• Where x equals -1

• Where x equals 1

• Where y equals 0

What is the y-intercept of the quadratic function represented by the table?

• 0, 3

• 0, -3

• 3, 0

• -3, 0

What are the final y-intercepts for the table and graph?

• 3, 0 for the table and -3, 0 for the graph

• 0, -3 for the table and 0, 3 for the graph

• -3, 0 for the table and 3, 0 for the graph

• 0, 3 for the table and 0, -3 for the graph
