Answer:
OPTION D
Step-by-step explanation:
We have to determine which option determines the function given above.
To determine the function, just substitute the values and compare LHS and RHS.
we have 



Here,
is the domain and
is the co-doamin.
Therefore, 
Now, OPTION A: 
Substitute x = 4. We get f(x) = 3
18.
So, OPTION A is rejected.
Similarly, OPTION B: 
Substitute x = 4. We get f(4) = 22
18.
It is rejected as well.
Now, for OPTION C: 
Substitute x = 4. We get f(4) = -3
18.
So, OPTION C is also rejected.
OPTION D: 
Substitute x = 4. We get f(4) = 18.
Substitute the remaining points in domain as well. We notice that it exactly matches the given function. So, OPTION D is the answer.
Answer:
So far we know Jack has a bag of fruits and he if he randomly picks up a fruit from he will most likely get an apple. From this, we know that the percentage of an apple being picked is at least above 50%. And since it is likely we know it could be close to a 70 : 30 ratio.

Answer: 300 years
Step-by-step explanation:
Let x be the age of Florentine statue,
Thus, According to the question,
The age of Roman statue = 3 x
After 100 years, the age of Florentine statue = x + 100
And, the age of Roman statue = 3x + 100
Again according to the question,
3x + 100 = 2( x + 100)
3x + 100 = 2x + 200
3x - 2 x = 200 - 100
x = 100
Therefore, the present age of Roman statue = 3 × 100 = 300 years
