Answer: see below
Step-by-step explanation:
1. (i) y = f(x) + 2
shift the graph UP 2 units (x, y) → ( x, y + 2)
A (0, 3) → (0, 5)
B (1, 0) → (1, 2)
C (4, 3) → (4, 5)
(ii) y = f(x + 4)
shift the graph 4 units RIGHT (x, y) → (x + 4, y)
A (0, 3) → (4, 3)
B (1, 0) → (5, 0)
C (4, 3) → (8, 3)
(iii) y = -f(x + 1)
shift the graph 1 unit RIGHT and reflect across the x-axis
(x, y) → (x + 1, -y)
A (0, 3) → (1, -3)
B (1, 0) → (2, 0)
C (4, 3) → (5, -3)
(iv) y = -f(x) - 2
shift the graph 2 units DOWN and reflect across the x-axis
(x, y) → (x, -(y - 2))
A (0, 3) → (0, -5)
B (1, 0) → (1, -2)
C (4, 3) → (4, -5)
7. (i) A is the y-intercept. Let x = 0 and solve for y
(ii) B is the x-intercept. Let y = 0 and solve for x
(iii) C is the vertex. Use x = -b/2a, then plug x into the equation to solve for y.
