Find the equations of any horizontal tangents to the curve
y = x^3 - 3x ^2 - 9x + 2

Answers:

y = -25

y = 7

Step-by-step explanation:

Find the derivative of the function.

The zeros of the derivative are the local extrema (Maximum & Minimum)

Take out the greatest common factor, 3, to get this equation:

Factor out the brackets.

You are left with two possible values for x:

x = 3

x = -1

By substituting each value into the original function , you get the equation of any horizontal tangents to the curve.

When x = 3:

      Meaning y = -25

When x = -1:

   Meaning  y = 7

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?
