1) Find a pointsatisfying the conclusion of the MVT for the function()=7^(2/3)on the interval[0,512].

(Use symbolic notation and fractions where needed.)

2) Find the critical point and the intervals on which the function is increasing or decreasing and apply the First Derivative Test to each critical point on the interval[/2,/2].

()=2^()cos()

(Use symbolic notation and fractions where needed.) 3) Which value ofsatisfies the conclusion of the MVT for the function()=2^253on the interval[1,2]?

(Use symbolic notation and fractions whereneeded.)
