x² ≠ 4
√x² ≠ √4
x ≠ ±2
x ≠ -2 and x ≠ 2
(-∞, -2) ∨ (-2, 2) ∨ (2, ∞)
Range: y ≠ 1
(-∞, 1) ∨ (1, ∞)
Intervals: Increasing: (0.25 , ∞)
Decreasing: (-∞, 0.25)

Y = (x - 2)/3
3y = x - 2
x = 3y + 2
Therefore, the inverse of y = (x - 2)/3 is y = 3x + 2
The required relationship shown by the graph is the exponential relationship 
. Option a is correct,
Given that,
A graph has been shown, showing the data, what is the relationship between the number of bacteria with time is to be determined.
<h3>What is a graph?</h3>
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Since the recorded value from the graph is
At, t = 1 ; n = 2
At t = 2 ; n = 4
At t = 3 ; n = 8
At t = 4 ; n = 16
At t = 5 : n = 32
Here the above data show the exponential relation between n and t with the base value 2 i.e.
Thus, the required relationship shown by the graph is the exponential relationship of . Option a is correct,

Answer:
42/81 or 0.5185185
Step-by-step explanation:
7/9 × 2/3
The hcf of 9 and 3 is 9
7/9 × 2/3
2/3 × 3= 6/9
7/9× 6/9 = 42/81 or 0.5185185
Answer:
52:3
Step-by-step explanation:
divide 260 by 5 and 15 by 5
260 divided by 5 = 53
15 divided by 5 = 3
260:15 = 52:3
