Creating tables from linear functions: Generate a table for the linear function y = -2x + 3 for x values -3, -2, -1, 0, and 1.

The table for the linear function y = -2x + 3 is: (-3, 9), (-2, 7), (-1, 5), (0, 3), (1, 1)

The table for the linear function y = -2x + 3 is: (-3, 6), (-2, 5), (-1, 4), (0, 3), (1, 2)

The table for the linear function y = -2x + 3 is: (-3, -6), (-2, -5), (-1, -4), (0, -3), (1, -2)

The table for the linear function y = -2x + 3 is: (-3, 3), (-2, 2), (-1, 1), (0, 0), (1, -1)

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

D: {1, -3, -4,} R: {0, 1, 2, -4}

D: {0, 1, 2, 3, 4} R:{1, -3, -4}

D: {0, 1, 2, -4} R: {1, -3, -4, 1}

Does the graph represent a function?

No, because the vertical line test shows there are repeating input values

Yes, because the vertical line test shows there are no repeating input values

{-2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
