Answer:
B 2
Step-by-step explanation:
The computation of the value of f(x) in the case when x = 2 is shown below
As per the question, following function is given
F(x) = (1 ÷ x) + 2
Based on this, the x = 2
Now put the x value in the above equation
So,
= (1 ÷ 2) + 2
= (1 + 4) ÷ 2
= 5 ÷ 2
= 2.5
Hence the closet number is 2
Therefore the value of f(x) in the case when x = 2 is 2
Hence, the correct option is b.

Answer: price of the watch before the discount is £23.5825
Step-by-step explanation:
Let x represent the original price of the watch.
Jason went shopping he bought a watch and a pair of trainers for a total price of £53.55. This price includes 15% loyalty discount. The value of the discount is
15/100 × 53.55 = 8.0325
This means that the original cost of both items is
53.55 + 8.0325 = 61.5825
Before the discounts, the trainers were priced at £38. Therefore,
38 + x = 61.5825
x = 61.5825 - 38
x = 23.5825
Answer:
5/9
Step-by-step explanation:
f(x) = 5 * 3^x
Let x = -2
f(-2) = 5 * 3^-2
We know a^-b = 1/a^b
= 5 * 1/3^2
= 5/9
