hunter left his house at time zero and drove to the store, which is 18 blocks away, at a speed of 3 blocks per minute. Then he stopped and went into the store for 4 minutes. From there, he drove in the same direction at a speed of 1 block per minute until he got to the bank, which is 3 blocks away from the store. He stopped at the bank for 5 minutes. Then drove home at a speed of 7 blocks every minute.

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
