d
Step-by-step explanation:
A. It passes the vertical line test
1 ft = 12 inches
(1 ft)^3 = (12 inches)^3
1 cubic foot = 1728 cubic inches
You'll multiply by the conversion factor (1278 in^3)/(1 ft^3) to convert from cubic feet to cubic inches. Notice how the cubic feet ft^3 unit is at the bottom of the conversion fraction, so that the cubic feet units cancel.
Answer: A) multiply by 1728
646/3=x
To check it: x*3 should =646
Just draw the graphs, and you should find y = 10x² is the only graph narrower than the given one.
