How does the graph of g(x)=2⌈x⌉ differ from the graph of f(x)=⌈x⌉? a. multiplying by 2 compresses the graph of g(x)=2⌈x⌉ vertically by a factor of 2. b. multiplying by 2 stretches the graph of g(x)=2⌈x⌉ vertically by a factor of 2. c. multiplying by 2 shifts the graph of g(x)=2⌈x⌉ up 2 units. d. multiplying by 2 shifts the graph of g(x)=2⌈x⌉ down 2 units.

Lindsay is creating a bridge out of dried pasta and glue. in her plans, she sketches the graph to determine the lengths of the noodles, in centimeters, needed for the arch to increase the length of the bridge in 1 centimeter increments.which function did lindsay use to create her design? f(x) = (x – 5)2 + 8 f(x) = –(x + 5)2 + 8 f(x) = 0.5(x + 5)2 + 8 f(x) = –0.5(x – 5)2 + 8

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)

Rachel is studying the population of a particular bird species in a national park. she observes every 10th bird of that species that she can find in the park. her conclusion is that the birds living in the park who belong to that species generally feed on insects. rachel's sample is . based on the sample she picked, rachel's generalization is
