Find the midpoint of the line segment joining ( -1,4), (-5,-2)

so, converting firstly the mixed fractions to improper fractions and then "adding".

c > -10.55

step-by-step explanation:

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)
