Question

Which equation represents the vertex form of the equation y = x2 + 2x - 6?

Answer 1

Answer:

y=(x+1)^2-7

Step-by-step explanation:

y=x^2+2x-6=x^2+2x+1-7

y=(x^2+2*1*x+1^2)-7

y=(x+1)^2-7

vertex form equation is y=a(x-h)^2+k

of equation y=ax^2+by+c

so a is 1

h is -1 because (x+1)=(x-(-1))

k is -7
