HELP ME PLEASE!!What are the domain and range of the function f(x)=1/4(x^3+6x^2+5x-4)

choices:
domain: (-5,0)
range: (-2,0.5)

domain: (-3.5, 2.5)
range: (-0.5, -1.3)

domain: (infin., 1/4)
range: -4, infin.)

domain: (-infin., infin.)
range: (-infin., infin.)

Answers

Answer 1
Answer:

Answer:

domain: (-infin., infin.)

range: (-infin., infin.)

Step-by-step explanation:

This is an odd degree polynomial which forms a sideways S shape starting low and ending high. Since nothing restricts the function from having an output for every real number input, the domain and range are (-infin., infin.).

Please help! Correct answer only!For a fundraiser, there is a raffle with 100 tickets. One ticket will win a $150 prize, and the rest will win nothing. If you have a ticket, what is the expected payoff?


$ ___

Answers

Answer:

Expected Payoff ⇒ $ 1.50 ; Type in 1.50

Step-by-step explanation:

Considering that 1 out of the 100 tickets will have a probability of winning a 150 dollar prize, take a proportionality into account;

100 - Number of Tickets,\n1 - Number of Tickets You Can Enter,\n\n1 / 100 - Probability of Winning,\n$ 150 - Money Won,\n\nProportionality - 1 / 100 = x / 150, where x -

Thus, Solution ; Expected Payoff ⇒ $ 1.50

find the volume of a 4 ft by 2 ft by 3 ft rectangular prism with a cylindrical hole, radius 6 in., through the center

Answers

V = lwh - πr²h
V = (4)(2)(3) - 3.14(¹/₂)²(3)
V = (8)(3) - 3.14(¹/₄)(3)
V = 24 - 3.14(³/₄)
V = 24 - 2.355
V = 21.645 ft³
V = 259.74 in³

Solve the equation: √x+1 = x-1

Answers

√(x+1) = x - 1 \n \n x + 1 = (x - 1)^2 \n \n x + 1 = x^2 - 2x + 1 \n \n x = x^2 - 2x \n \n x - x^2 + 2x = 0 \n \n 3x - x^2 = 0 \n \n x(3 - x)= 0 \n \n x = 0,3 \n \n x = 0 \ is \ false \n \n x = 3

The final result is, x = 3.

The solutions we gather were x = 0,3. 
We dropped x = 0 from the equation since it does not become true, so we are left with x = 3. 
√x + 1 = x - 1
           ↓
      √x = x - 1 + 1
           ↓
      √x = x

Since 1 is the only real number whose square root equals itself, we can safely assume that x = 1.
Hope that helped! =)
