a. Graph y = 2x – 4 by hand.
b. For the equation y = 2x - 4, find all outputs for the input x = 3. Explain by using arrows on your graph in part (a). State how many outputs there are for that single input.
c. For y = 2x - 4, how many outputs originate from any single input? Explain in terms of drawing arrows.
d. Using your equation, find all outputs for the input x = 2. Explain by using arrows on your graph in part (d). State how many outputs there are for that single input.
e. For your equation, how many outputs originate from any single input? Explain in terms of drawing arrows.
f. For any equation of the form y = mx + b, how many outputs originate from a single input? Explain in terms of drawing arrows.
