Answer:
The domain of the function is -4 ≤ x ≤ 9 ⇒ D
Step-by-step explanation:
- The domain of any relationship is the values of the input
- The domain of the function f(x) = y is the values of x which make the function defined
In the given figure
∵ There are 5 intervals between 0, 10 and 0, -10 on the x-axis
∴ Each square = 2
∵ There are 5 intervals between 0, 10 and 0, -10 on the y-axis
∴ Each square = 2
→ Find the coordinates of the starting and the ending point of the graph
∵ The starting point located 2 squares left and 2 squares down
∴ The starting point of the graph of the function is (-4, -4)
∵ The ending point located 4.5 squares right and 4 squares up
∴ The ending point of the graph of the function is (9, 8)
→ That means the x-coordinates of all points on the graph is from -4 to 9
∴ All values of x-coordinates on the function are located on -4 ≤ x ≤ 9
∵ The domain of the function is the values of x
∴ The domain of the function is -4 ≤ x ≤ 9
