Answer: Domain: x = All Real Numbers (-∞, ∞)
Range: y ≤ 1 (-∞, 1]
Explanation:
y = -2(x - 4)² + 1
The equation is in vertex form → vertex = (4, 1)
The leading coefficient is negative so it will be a max at y = 1
Range: y ≤ 1.
This is a polynomial so there are no restrictions on x.
Domain: x = All Real Numbers
