The function f(x) = x2 + 10x - 3 writers in vertex form is f(x) = (x + 5)2 - 28. what are the coordinates of the vertex?

General formula of the parabola in vertex form is

f(x) =(x-h)² +k, where (h,k) is a vertex of the parabola.

f(x) = (x + 5)²- 28

h= -5, k = -28,

so (-5, -28) is a vertex of the given parabola.

Answer is A.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
