Question

Use the picture below to give the requested information about the linear functions. Which pair of lines is parallel? Which line has the largest y-intercept? which lines have the same y-intercept? of those which one has the largest slope? Honest Al & Trustworthy Mike both run Rent-A-Car dealerships. Honest Al: "I rent cars for $48 a day and 5 cents a mile." Trustworthy Mike: "I rent cars $39 a day and 8cents a mile." Give formulas for the cost of renting a car for one day as a function of the distance traveled: Honest Al: & Trustworthy Mike: Who should you rent from if you have to travel 150 miles? How much will it cost: (units) Who should you rent from if you have to travel 550 miles? How much will it cost (units) Find the distance such that both places charge the same: (units) How much will it cost: (units) Each table below represents a function. Decide if each function is increasing or decreasing and if it is concave-up, concave-down, or neither. f(x) is: increasing decreasing f(x) is: concave-up concave-down neither g(x) is: increasing decreasing g(x) is: concave-up concave-down neither h(x) is: increasing decreasing h(x) is: concave-up concave-down neither p(x) is: increasing decreasing p(x) is: concave-up concave-down neither

Explanation / Answer

10. a) L1 and L2 are parallel (as distance between the 2 lines is same everywhere)

b) From graph, we see L1 has the largest y-intercept.

c) L2, L3 have same y-intercept (as they intersect at the same point on y-axis) and L3 has largest slope.
