1. The function h is the sum of the functions f(x)=3x+5 and g(x)=2x^2 - 6x - 2. Which represents h? A.h(x) = 5x^2 - x - 2 B. h(x) = 2x^2 - 3x + 3 C. h(x) = 2x^2 - 9x + 7 D. h(x) = -3x + 3

according to the question, function h means h(x) is sum of f(x) and g(x) which means f(h)= f(x)+g(x)
where it is given that f(x)=3x+5 and g(x)= 2x^2-6x-2
now, h(x)= f(x)+g(x)
=3x+5+(2x^2-6x-2)
=3x+5+2x^2-6x-2
=2x^2-3x+3
option B is right .
