Continuous VS Discrete

Continuous VS Discrete

“Birds’ Eggs “ Think About Plotting Points Discrete vs Continuous Titling and Labeling Graphs The Relationship of the Points

Which ordered pair is a solution of 2x – 3y = 24? (-6, 4) (-6, -4) (6, -4) (6, 4) Why is the point you chose a solution?

Make a table and graph. Hint: Pay attention to the domain. y = -3x + 1 Domain: {-1, 0, 1, 2} x y Is this graph discrete or continuous? State the range.

Make a table and graph. Hint: Pay attention to the domain. f(x) = -x + 2 Domain: x > 0 x f(x) State the range. Is this graph discrete or continuous?

Sometimes you need to solve for y and then graph 2x - y = 4 Domain: {-1, 0, 1, 2} x f(x) State the range. Is this graph discrete or continuous?

Graph: 3x + 2y = 6 y x 3x + 2y = 6 Domain: {x x < 0} State the range. Is this graph discrete or continuous?
