Answer:
y = 2 (x + seven-halves) squared minus one-fourth [y = ]
Step-by-step explanation:
We know that,
vertex form is y = a(x-h)² + k
vertex is (h, k)
Now,
Given that the equation is -
y = (x+3)² + (x+4)²
= x² + 3² + 2×3×x + x² + 4² + 2×4×x
= x² + 9 + 6x + x² + 16 + 8x
= 2x² + 14x + 25
=
=
=
=
∴ we get
The vertex form is -
y =
So,
The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y = )
