Carlos’s score on a video game after x minutes can be modeled by the graph. Estimate the x-coordinates at which the relative maxima and relative minima occur. Describe the meaning of the extrema in the context of the situation.

• The relative maxima occur at x=3 x=5

• The relative maxima occur at x=2 x=3

• The relative maxima occur at x=2 x=5

• The relative maxima occur at x=0 x=3

Carlos’s score on a video game after x minutes can be modeled by the graph. Estimate the x-coordinates at which the relative maxima and relative minima occur. Describe the meaning of the extrema in the context of the situation.

• the relative minimum occurs at x=0

• the relative minimum occurs at x=3

• the relative minimum occurs at x=5

• the relative minimum occurs at x=2

Carlos’s score on a video game after x minutes can be modeled by the graph. Estimate the x-coordinates at which the relative maxima and relative minima occur. Describe the meaning of the extrema in the context of the situation.

• The relative maximum at x=2 represents his highest score

• The relative maximum at x=5 represents his highest score

• The relative maximum at x=0 represents his highest score

• The relative maximum at x=3 represents his highest score

Carlos’s score on a video game after x minutes can be modeled by the graph. Estimate the x-coordinates at which the relative maxima and relative minima occur. Describe the meaning of the extrema in the context of the situation.

• The relative minimum at x=2 represents a low point in his score

• The relative minimum at x=3 represents a low point in his score

• The relative minimum at x=5 represents a low point in his score

• The relative minimum at x=0 represents a low point in his score

Describe the end behavior of the function.

• As x→∞, y→∞ x→-∞, y→∞

• As x→∞, y→∞ x→-∞, y→-∞

• As x→∞, y→-∞ x→-∞, y→-∞

• As x→-∞, y→∞ x→-∞, y→-∞

The graph shows the height y of a ball that is thrown from a balcony after x seconds. Describe and interpret the end behavior in the context of the situation.

• Because time cannot be negative the function is not defined for x<0

• Because time cannot be positive the function is not defined for x<0

• Because time cannot be negative the function is not defined for x>0

• Because time cannot be positive the function is not defined for x>0

The graph shows the height y of a ball that is thrown from a balcony after x seconds. Describe and interpret the end behavior in the context of the situation.

• So, there is end behavior as x→−∞

• So, there is no end behavior as x→−∞

Mika and her friends are using a ride-sharing service to take them to a concert. The function models the cost of the ride, f(x), after x miles. Describe the end-behavior of f(x) and interpret it in this context.
