Best ResponseYou've already chosen the best response.1i THINK you have to set it up like this: 3(x+3)^2+1

Best ResponseYou've already chosen the best response.1and if its g(1) then you plug in 1 for x

Best ResponseYou've already chosen the best response.1which would get you 2 so it'd be 3(2)^2+1 which is 3(4)+1 12+1=13

Best ResponseYou've already chosen the best response.1Select the equations that are parallel and perpendicular to y = −3x − 1 and that pass through the point (3, 1). A. parallel: y = −3x + 6 perpendicular: y = (1/3)x + 2(2/3) B. parallel: y = −3x + 10 perpendicular: y = (1/3)x C. parallel: y = (1/3)x perpendicular: y = −3x D. parallel: y = (1/3)x + 1 perpendicular: y = 3x − 1
