Question

Could some please help me with this problem?

Answer 1

-0.5

Answer 2

it it Lagranj theorem?

Answer 3

Do you mean take the derivative?

Answer 4

derivative is -2x = slope at point c

Answer 5

Lol, is this web assign?

Answer 6

nope! and Yes that's what I got and when I solved for f'(c) I got 7

Answer 7

is this problem solved?

Answer 8

No, I'm still working on it. I found the derivative, which was 12x, but the I tried to find (2) but the answer I got isn't correct.

Answer 9

the problem says that you must compute the value of the expression \[\frac{ f(b)-f(a) }{ b-a }\]

Answer 10

and for that I got 7, but it isn't right

Answer 11

compute the derivative of f(x) and equate it to 7.

Answer 12

for that I got -7/2

Answer 13

the value 7 is not right. you must have made an error in the subtraction

Answer 14

Dont we do f(0)-f(-1)/0-(-1)?

Answer 15

f(b) = 4, while f(a) = 3

Answer 16

i sense that your mistake was the subtraction in the numerator.

Answer 17

Thats what I got too, so I ended up with this 4+3/0+1

Answer 18

it says f(b) MINUS f(a). the numerator should be 1, not 7.

Answer 19

So the equation would equal 1 then?

Answer 20

that is right.

Answer 21

and the value of c in the problem is the value of x in your equation, which is -1/2

Answer 22

I tried that as my answer and it says that it is incorrect

Answer 23

Wait that's my c value. Nevermind, it's correct

Answer 24
