Question

Which of the following is the graph of the function shown below?

y = x2 + 4x + 3

Answer 1

For this you would use the equation of the line of symmetry which is x = -b/2a

x = -4/2(1) = -4/2 = -2
so, x = -2

then you would plug -2 in the x-value of the original equation.

Answer 2

@CloverRacer so the answer would be W?

Answer 3

yes correct(: because the coordinates are (-2, 1)
