Its vertex is (-3 , -5)
Its axis of symmetry is at x = -3
The direction of opening of it is upward
Step-by-step explanation:
The vertex form of the quadratic function is:
y = a(x - h)² + k, where
1. The coordinates of its vertex point are (h , k)
2. Its axis of symmetry is at x = h
3. The direction of opening is upward if a > 0, and downward if a < 0
∵ y = 2(x + 3)² - 5
∵ y = a(x - h)² + k
∴ a = 2 , h = -3 and k = -5
∵ The coordinates of the vertex are (h , k)
∴ The vertex is (-3 , -5)
∵ The axis of symmetry is ta x = h
∴ The axis of symmetry is at x = -3
∵ a = 2 and 2 > 0
∴ The direction of opening is upward
Its vertex is (-3 , -5)
Its axis of symmetry is at x = -3
The direction of opening of it is upward
