Solve for x: x - 1 = 4x + x - 8 + 3x

x-1= 4x +x -8 +3x  (combine like terms on the right side)

x-1= 8x -8  (subtract 8x from both sides, and the same time add 1 to both sides

-7x= -7  (divide by -7 on both sides)

x=1

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
