Directions: Graph each equation below. Give the axis of symmetry, vertex, domain, range, and zeros. y = x2 +10x + 21

answer:

24pi or letter c

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)
