Question

I’m not sure on how are you suppose to graph this without knowing what the x’s are and a calculator?

Answer 1

The answer is shown in the plotted graph attached with the answer.

Explanation:

i) Let y = f(x)

ii) According to the first equation we will consider x = -6, -5, -4, -3, -2, -1, 0, and

1

Therefore x and y = x + 4 for -6 ≤ x < 2

• -6 -2
• -5 -1
• -4 0
• -3 1
• -2 2
• -1 3
• 0 4
• 1 5

iii) y = 6 when x = 2 is the second equation given for the graph

iv) x y = -x + 2 for x > 2 is the third equation given

• 3 -1
• 4 -2
• 5 -3
• 6 -4
