Answer 4

you need to find the derivative of the function
use the quotient rule

Answer 5

but how where we have to put the slope

Answer 6

can you do that . Have you done any calculus?

Answer 7

the slope will be the derivative and you equate it to -12/25
Then solve for x

Answer 8

can you plz show

Answer 9

i know how to find the derivation of this equation using quotient

Answer 10

y' = 3(x - 4) - 3x * 1
-------------
(x - 4)^2

= -12
-----
(x - 4)^2

Answer 11

now this equlas -12/25

so we have

-12 -12
----- = ------
(x - 4)^2 25


Solve this for x.

Answer 12

as the numerators are both the same we can write

(x - 4)^2 = 25

Answer 13

now its easy

once you have found the 2 values of x
plug them into the original function to find the y-values of the 2 points.

Answer 14

OK?

Answer 15

i have to go
