1.
A graph is formed by plotting all pairs (x,y), such that y is f(x), for a certain function f.
for example:
Take a look at the graph. (x, y)=(3, 5) is on the graph. This means that f(3)=5 (because f(x)=y)
2.
The real solutions of a function f, are those points x, such that f(x)=0.
in the graph we see no point (x, 0), so there are no real solutions.

tip: when dividing by 8 see if the 3 last digits are able to be divided by it
Answer:
Step-by-step explanation:
a)
The answer is greater than 450 because the percentage is less than 100%
b)
36% = 36/100 = 0.36
450/0.36 = 1250
how many people were surveyed?:
1250
<u>Answer:</u>
Among the given numbers, only 2736 and 45 are divisible by both 3 and 9 .
<u>Step-by-step explanation: </u>
We know that an integer is divisible by 3 or 9 iff (if and only if) the sum of it's digits are divisible by 3 or 9 respectively.
Now,
sum of the digits of 1221 = (1 + 2+ 2 + 1)= 6 which is divisible by 3 but not divisible by 9 , hence, 1221 is divisible by 3 but not by 9.
and,
sum of the digits of 2736 = (2+ 7+ 3 + 6)= 18 which is divisible by both 3 and 9 , hence, 2736 is divisible by both 3 and 9.
and,
sum of the digits of 45 = (4 + 5)= 9 which is divisible by both 3 and 9 , hence, 45 is divisible by both 3 and 9.
