Answer
Find out the value of g(3) by using the function g(x) = x² + 2 given in the question .
To proof
The function given in the question is
g(x) = x² + 2
Take x = 3
put x = 3 in the g(x) = x² + 2
than it becomes
g(3) = 3² + 2
solving the above
we get
g(3) = 9 + 2
g(3) = 11
Thus g(3) = 11 and option (c) is correct .
Hence proved

Story : A Dog’s Tale by Mark Twain
1. Using a dog as narrator gives the passage a tone of —
• objectivity
• formality
• bitterness

2. What literary device is used in the sentence “She had one word which she always kept on hand, and ready, like a life-preserver”?

4. According to the author, what would bring such happiness to the dogs as he describes at the end of the story?
• They helped the author’s mother find the words she used, so they especially enjoyed watching her use them.
• They knew the meaning of “supererogation” and realized they were listening to a funny joke.

• They were generally happy dogs who often expressed a great deal of joy.
5. “A Dog’s Tale” uses the topic of animal communication in order to —
• show how dogs really communicate
• explain how animals learn from humans
• demonstrate that dogs are smarter than most people
• poke fun at human behavior
6. The amount of time that passes during this story is most likely —
• 10 hours
• 10 days
• 10 months
• 10 years
7. An underlying theme in this story is that —
•many people use words without knowing their meanings
• dogs know more than people realize
• family loyalty takes top priority
• strangers are almost always suspicious
8. Since the author used first person, readers are left to wonder —
• how the author felt about his mother
• how strangers reacted to his mother’s word knowledge
• what the author’s mother was thinking
• whether or not the author’s mother knew the meanings of all the words she used
Answer:
Su=10
Explaination:
So from s to u on the nunebr line is worth 2x-12. So what is s to u worth? Well. S to t on the number line = x-7. T to u =6. And 2 x is worth 12 more than s to u, using th e expression. X has to be at least 8 because otherwise the x-7 wouldn't work, and u might get s to u = 0 or a negative number.
Say x was 13, then 13 - 7 =6. So S to t =6. And r to u =6. So s to u =12. (6+6). Then check if the expression fits this answer of 12. 2x - 12. 2x = 26. 26-12=14, which doesn't match.
Let's try 14. 14-7=7. Then s to u = 7+6=13. The expression: 2x= 28. 28-12=16. 13 and 16 dont match. So we have got further away from what we need. Why don't we try going in the opposite direction. Rather than testing 13 and +1, let's now - 1 and try 12.
If x=12, then s to t =12-7=5. And s to u =6+5=11. The expression: 2x=24.-12=12. We are very close now with 11 and 12.
Lets test x=11!
S to t = 11-7=4. 4+6=10. So s to u =10.
2x=22. 22-12=10. So the expression works and the number line measurements.
The answer is su=10 and x=11.
