ABC is a triangle and m is the midpoint of BC a line through c parallel to ab cuts am produced at x. Prove mx =ma

combine all like terms then its just a 2 step equation

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)

i believe b is the answer
