Hi tutor, please provide a correct answer and explanation

Multiplication of functions

The area A of a trapezoid is one-half the height h times the sum of the bases, b and b2 . Using the illustration below, what is the area of the trapezoid? 3x - 7 X + 2 2x + 1Which of the following notations do not represent the product of two functions x) and 90B) 3' f(2=)9($) f 0 9(3) f(9($)) it) -9(-1=) Determine the validity of the following equation: f(=!=) 11(3) = 903) f(=l=) sometimes true always true not enough information given never true Determine the validity of the following statement. The function (!)(x) = 241 235 may be further simplified. never true always true sometimes true not enough information given\f
