Determine which of the functions below is differentiable at each given point where x=a. Using Theorem 2.3.1, make conclusions regarding the continuity of the given functions
at x = a. (Note: What is being emphasized here is the use of the theorem; continuity
checked separately from differentiability by merely using the definition.)

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

this answer is !
