Which of the following statements is true about f(x)?

The correct option is D.

Step-by-step explanation:

A point is called relative maximum if it is higher than the points directly beside it on both sides. In other words, the maximum point over a small interval is called relative maximum.

A function can have more than one relative maximum. It is also known as local maxima.

A point is called relative minimum if it is a point that is lower than the points directly beside it on both sides. In other words, the minimum point over a small interval is called relative minimum.

A function can have more than one relative minimum. It is also known as local minima.

From the given graph it is cleared that F(x) has relative maximum at x=-1 and a relative minimum at x=0.8.

Therefore the correct option is D.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
