Question

Give a formula for the extended function that is continuous at the point x = -7.

(x^2-49)/(x+7)

Answer 1

can i give u the answer?

Answer 2

0

Answer 3

(x-7)(x+7)/(x+7) =x-7

Answer 4

yeah

Answer 5

0 is the answer

Answer 6

i need formula not the answer

Answer 7

o, well jhonny has it then i think

Answer 8

7th graders dont know how to do calc

Answer 9

hey dont be mean!

Answer 10

why would you answer this question if you know you cant answer

Answer 17

i knoow tht was not the question u were asking

Answer 18

ok hold on i am getting to the solving.

Answer 19

you cannot solve it

Answer 20

x=-7
(-7^2-49)/(-7+7)
(49-49)/(-7+7)
0/0
0

Answer 21

okay if you read the question, it says give the formula for the extended function that is continous at x=-7, do you know what that means?

Answer 22

nah not really

Answer 23

exactly, all you did was plug in -7 where you saw x, but that is not what the question is asking us to do

Answer 24

so, atleast i tried...

Answer 25

yeah sure you tired, you tired answering the wrong question

Answer 26

x-7 if x is not equal to -7
Now we take the limit as x ===>7, (x-7), this gives us zero.

Thus we define the function (x^2-49)/(x+7) only if x is not equal to -7
