Each exterior angle of a regular polygon measures 45 degrees. how many sides does the polygon have

8 sides

Step-by-step explanation:

because you use the formula for exterior angles; , you plug in the number of sides in the denominator and then divide 360 by n

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)

it is impossible.
