I need step by step help with this problem. I don’t even know where to start with this problem. It doesn’t pertain to any of the class work or homework.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

The functions f(x) and g(x) are shown in the graph f(x)=x^2 what is g(x) ?
