What are the domain and range of the function?<br> f(x) = ^3 square x - 3
DerKrebs [107]

Step-by-step explanation:

f(x) = \sqrt[3]{x - 3}

The domain of a function are the values of x that you can plug into the function f(x).

Values inside of a root must be non-negative, which means that x - 3 must be greater than or equal to zero. We can set up an equation to find the domain:

x - 3 \geq 0

x \geq 3

With this, we know the domain of the function is [3, \inf).

The range of a function are the values that f(x) can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is [0, \inf).

How do you solve: f(x) = -x2e-x<br> +2xe-x , finding the zero's of f.
Maksim231197 [3]

Answer:

0 and 2

Step-by-step explanation:

f(x) = -x^2e^{-x}+2xe^{-x}

To find zeros set f(x)=0  and solve for x

0 = -x^2e^{-x}+2xe^{-x}

0 = -e^{-x}(x^2-2x)

now factor out x

0 = -xe^{-x}(x-2)

set each factor =0 and solve for x

x=0

-e^{-x}=0 no solution for x

x-2=0, x=2

zeros of f  are 0 and 2

What polynomails has the roots of -6, -4 ,and 1? A)x³-9x²-22x+24 B) x³-x²-26x-24 C) x³+x²-26x+24 D)x³+9x²+14x-24.
never [62]

Answer:

x = 1 or x = -4 or x = -6 thus d: is your answer

Step-by-step explanation:

Solve for x over the real numbers:

x^3 + 9 x^2 + 14 x - 24 = 0

The left hand side factors into a product with three terms:

(x - 1) (x + 4) (x + 6) = 0

Split into three equations:

x - 1 = 0 or x + 4 = 0 or x + 6 = 0

Add 1 to both sides:

x = 1 or x + 4 = 0 or x + 6 = 0

Subtract 4 from both sides:

x = 1 or x = -4 or x + 6 = 0

Subtract 6 from both sides:

Answer:  x = 1 or x = -4 or x = -6
