Question

Find the domain of the graphed function

Answer 1

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
