Step-by-step explanation:
Recall the form of the difference of squares.

Now let's apply it to your numbers:

Simplify:

Answer:
The function increasing ⇒ 3 ≤ x ≤ 6 answer C
Step-by-step explanation:
∵ The vertex of the parabola is (3 , -6)
∴ The minimum value = -6 at x = 3
∵ The left part of the parabola is decreasing because the value of y decreased from 3 to -6 when 0 ≤ x ≤ 3
∵ The right part of the parabola is increasing because the value of y increased from -6 to 3 when 3 ≤ x ≤ 6
∴ The function is increasing at interval 3 ≤ x ≤ 6
month 4: 13.25*4=53. 53+50 = 103
month 4: 25.75*4 = 103
They both cost $103 on month 4
