The graph shows a polynomial function f. Polynomial function g is defined by g(x)=x^2(3-x). Compare the maximum values and the end behavior of the functions f and g when x>0.

The sum of the first eight terms of an arithmetic progression is 9m + 14. the fifth term of the06 progression is 2m - 6, where m is a constant.given that the first term of the progression is 26,find the value of the common difference, d and thevalue of m.
