Let a and b be real numbers, where a≠b≠0 Which of the following functions could represent the graph on the right? f(x) = x (x – a)(x – b)2

f(x) = (x – a)(x – b)2

f(x) = x(x – a)³(x – b)

f(x) = x2(x – a) 2(x – b)2

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.
