Answer:

f⁻¹(x) = -4 + √x

Step-by-step explanation:

Switch the positions of x and y then solve for x.

f(x)=(x+4)^2\\x=(y+4)^2\\\sqrt{x} =y+4\\\sqrt{x} -4=y

Which of the following is a factor of 2xy + 8y − 8x − 32?
muminat
You could start by eliminating wrong answer(s):

(a) 5 is definitely not a factor of the given <span>2xy + 8y − 8x − 32,

(d) x^2 - 4x + 16 (not x2 - 4x + 16) is not a factor (it has no y terms)

On the other hand:

(b) 2 definitely divides evenly into </span>2xy + 8y − 8x − 32:  2(<span>xy + 4y − 4x − 16)

(c) x + 4 divides evenly into both xy + 4y and -(4x + 16):
                                           We get 2(x +4) [y - 4]</span>

What are the solutions to the quadratic equation below in factored form?
saw5 [17]

Answer:

\cfrac{-4}{3} and \cfrac{1}{2}.

Step-by-step explanation:

Equation:

\rm \:  \: (2x - 1)(3x + 4) = 0

Solution:

Set factors equal to zero,that is:

(2x - 1) = 0 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: ...(1)

(3x + 4) = 0 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: ...(2)

Solving for equation 1:

  • 2x - 1 = 0
  • 2x = 0  + 1
  • 2x =  1

  • \boxed{x =  \cfrac{  1}{2} }

Solving for equation 2:

  • 3x + 4 = 0
  • 3x = 0 - 4
  • 3x =  - 4

  • \boxed{x =  \cfrac{ - 4}{3} }

Hence,the solutions to the quadratic equation in factored form is \cfrac{-4}{3} and \cfrac{1}{2}.

\rule{225pt}{2pt}

Good luck on your assignment!
