Answer:
The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18 ⇒ b
The vertex = (-4, 18)
Step-by-step explanation:
The vertex form of the quadratic function f(x) is:
f(x) = a(x - h)² + k, where
- a is the coefficient of x²
- (h, k) are the coordinates of the vertex point
The most quickly reveals to find the vertex is the vertex form above
Look at the answer and try to find a similar form to the vertex form above
∵ g(x) = -2(x + 4)² + 18
∴ a = -2
∴ h = -4
∴ k = 18
⇒ That means this form is similar to the form above
∴ The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18
∴ The vertex = (-4, 18)
