The given function is,

The graph can be drawn as,
The period will be distance between two consequetive maximas,

Thus, period is correct.
The amplitude can be determined as,

Thus, amplitue is incorrect.
The range is,

Thus, the range is correct.
The midline is,

Thus, the midline is correct.
Thus, option (b) is the solution.
Complementary means the two angles add up to 90 degrees. Do 90 - 79 to find the other angle.
It's 11 degrees.
<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>
Make a table graph and go from 0-10 top for weeks and bottom for miles, label one Jeramy and the other one tony. For Jeremy add one mile each week and for timely add to by week 4 they both should have ran 10 miles
