Hey there! :)

Answer:

2nd option: (4, -136) is a relative minimum, (-2, 80) is a relative maximum.

Step-by-step explanation:

To begin, we can graph this equation (pictured on bottom of answer)

Relative minimums/maximums are the minimums and maximums of turning points of the graph. Observing the graph, we can see that:

(-2, 80) is a relative maximum because this is the maximum value at a turning point.

(4, -136) is a relative minimum because this is the minimum value at a turning point.

Tell whether the sequence is arthmetic. Common difference (-3,-7,-10,-14)
Burka [1]

Answer:

Not an arithmetic sequence

Step-by-step explanation:

For the sequence to be arithmetic there must be a common difference between consecutive terms.

- 7 - (- 3) = - 7 + 3 = - 4

- 10 - (- 7) = - 10 + 7 = - 3

- 14 - (- 10) = - 14 + 10 = - 4

The differences are not common , hence not an arithmetic sequence
