Answer:
In a coordinate axis, the horizontal line is called the x-axis, and the vertical line is called the y-axis.
1) Then if you have a point (x, y), to graph this you go at the horizontal axis to find the value x,
2) Starting from the point you already found, now you need to move y units in the vertical axis.
Now we want to graph the point (0, 3.5).
First we need to locate the value 0 in the horizontal axis, this is the point where both axes intersect.
Now we move 3.5 units, because the number is positive, we move 3.5 units upwards.
The graph of the point is shown below.
The answer is £287.98 is the correct answer

Step-by-step explanation:
<u>Answer</u>
B. f(n) = 56(0.5)^n-1
<u>Explanation</u>
f(n) (1) 56
(2) 28
(3) 14
(4) 7
To find the correct relation we have to test all of them.
A. f(n) = 28(0.5)^n
f(1) = 28(0.5)¹
= 28 × 0.5 = 14
<em>f(n) = 28(0.5)^n ⇒ Not correct relation</em>
B. f(n) = 56(0.5)^n-1
f(1) = 56(0.5)¹⁻¹ = 56×1
= 56
F(2) = 56(0.5)²⁻¹ = 56 × 0.5 = 28
F(3) = 56(0.5)³⁻¹ = 56 × 0.25 = 14
<em> f(n) = 56(0.5)^n-1 ⇒ It is the correct relation</em>
C. f(n) = 56(0.5)^n
f(1) = 56(0.5)¹ = 56 × 0.5 = 28
<em>f(n) = 56(0.5)^n ⇒ Not correct relation</em>
D. f(n) = 112(0.5)^n-1
f(1) = 112(0.5)¹⁻¹ = 112 × 1 = 112
<em>f(n) = 112(0.5)^n-1 ⇒ Not correct relation</em>
