The answer you chose is indeed correct!
Vertex form of a quadratic is y = a(x - h)^2 + k.
( h , k ) is the vertex and in the problem the very is ( 1, -3) so plug that in and:
y = (x - 1 )^2 + (-3) this is equal to:
y = (x -1)^ 2 - 3

Answer:
x = 5
Step-by-step explanation:
8x - 6x + 1 = 11
Add 6x to each side (because the 6 is negative)
8x + 1 = 11 - 6x
Subtract 1 from each side (because the 1 is positive)
8x = 10 - 6x
Subtract 6x from 8x
2x = 10
Divide by 2
x = 5
