Answer:

  y = 3/4x -7/4  or  y = 0.75x -1.75

Step-by-step explanation:

The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.

  y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

  y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points

  y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit

  y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction

  y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses

  y = 3/4x -7/4  or  y = 0.75x -1.75

What are the coordinates of the turning point for the function f(x) = (x - 1)3 - 3? A. (-1, -3)
Naddik [55]
ANSWER

The turning point is

(1,-3).


EXPLANATION


The function given to us is

f(x) = (x - 1) ^{3}  - 3

At turning point,
f  '(x) = 0

So we need to differentiate the given function and equate it to zero.



We using the chain rule of differentiation, we obtain,
f '(x) =3 (x - 1) ^{2}

We equate this to zero to obtain,




3 (x - 1) ^{2}   = 0



We divide through by 3.


(x - 1) ^{2}   = 0

We solve for x to get,

x - 1 = 0


x = 1


We substitute this x-value in to the function to obtain the corresponding y-value of the turning point.





f(1) = (1- 1) ^{3}  - 3




f(1) = 0 - 3


f(1) = - 3

Therefore the turning point is


(1,-3)

C is the correct answer.
