These two are the graphs

Answer 1

I tried everything but could seem to find the right answer

Answer 2

Did you try google?

Answer 3

yeah I couldnt find help there either, have no clue

Answer 4

Remember that the derivative is the slope of a line.

Answer 5

Hmmm

Answer 6

yes I've tried that too and I believe the slope of the line is equal to the slope of the tangent line too

Answer 7

and the slope of the tangent line equals the derivative

Answer 8

however I keep getting the wrong answer

Answer 9

That's so weird O.o

Answer 10

What answers are you getting?

Answer 11

Do they want you to get the derivative at certain points or what?

Answer 12

I got 2/3 for prime
but whats the te value of g(1)

Answer 13

they want k(1)

Answer 14

They want g(1) and k(1)? They don't want the derivative?

Answer 15

they want k(1) and k is equal to f(x)/g(x)
I got slope 2/3
for f(x)

Answer 16

and F'(1) is zero
because thats where u have an x intercept

Answer 17

and the equation simplifies to f(x)g(x)

Answer 18

over g(x)^2

Answer 19

Okay, so what are the graphs you posted?

Answer 20

those are the functions of f(x) and g(x)
they are the functions

Answer 21

So since f(1) = 1 and g(1) = 1.25, k(1) = 1 / 1.25

Answer 22

f'(1) = 2/3 since it rises 2 and runs 3 when x is 1

Answer 23

I don't see what's hard about this

Answer 24

How is g(1) = 1.25 when its not given

Answer 25

Well, from the left side you can see the slope is -2, so it has to hit at the half way point

Answer 26

Then it goes through the origin

Answer 27

So it is rising 2/1.5

Answer 28

4/3

Answer 29

thank you sooo much!! god blesss u !!! may u live happily ever after!!
