Question

Write the quadratic function in vertex form.

y = x2 + 4x + 7

Answer 1

y = (x + 2)2 + 3

i believe this is the answer, i just want conformation

Answer 2

\(\bf y=ax^2+bx+c \textit{ ,standard form}\\
y=a(x-h)^2+k \textit{ ,vertex form}\)

Answer 3

so you'd need to "complete the square" for that

Answer 4

so would i be correct?
