What is the completely factored form of f(x) = 6x3 – 13x2 – 4x 15? (x 1)(6x2 – 19x 15) (x 1)2(2x – 3) (x 1)(3x – 2)(5x – 3) (x 1

The completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

<h3>How to factor the expression?</h3>

The expression is given as:

f(x) = 6x³ - 13x² - 4x + 15

Expand the expression

f(x) = 6x³ - 19x² + 6x² + 15x - 19x + 15

Rewrite as:

f(x) = 6x³ + 6x² + 15x- 19x²   - 19x + 15

Factorize the equation

f(x) = (x + 1)(6x²- 19x + 15)

Expand (6x² - 19x + 15)

f(x) = (x + 1)(6x² - 10x - 9x + 15)

Factorize the expression

f(x) = (x + 1)(2x - 3)(3x - 5)

Hence, the completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

Which function below is the inverse of f(x) = X2 - 25?
viva [34]

Answer: f^{-1}(x)=  \sqrt{x+25} and f^{-1}(x)= - \sqrt{x+25}

Step-by-step explanation:

   To find the inverse, we will set f(x) equal to y, swap the x and y values, and then solve for y.

   Given:

f(x) = x² - 25

   Equal to y:

y = x² - 25

   Swamp x and y values:

x = y² - 25

   Add 25 to both sides of the equation:

y² = x + 25

   Square root both sides of the equation:

y=  \sqrt{x+25} and y=  -\sqrt{x+25}

   Interval notation:

f^{-1}(x)=  \sqrt{x+25},\text{and}\;f^{-1}(x)=  -\sqrt{x+25}
