F(x)=2x+1/x-1 then f^-1(1)​
olasank [31]

Answer:

  • f⁻¹(x) = (x + 1) / (x - 2)
  • f⁻¹(1 ) = - 2

Step-by-step explanation:

<u>Given function:</u>

  • f(x) = (2x + 1) / (x - 1)

<u>Find its inverse, substitute x with y and f(x) with x, solve for y:</u>

  • x = (2y + 1) / (y - 1)
  • x(y - 1) = 2y + 1
  • xy - x = 2y + 1
  • xy - 2y = x + 1
  • y(x - 2) = x + 1
  • y = (x + 1) / (x - 2)

<u>Substitute y with f⁻¹(x):</u>

  • f⁻¹(x) = (x + 1) / (x - 2)

<u>Find  f⁻¹(1 ):</u>

  • f⁻¹(1 ) = ( 1 + 1) / (1 - 2) = 2 / - 1 = - 2

How do you write out exponential growth of <br> 4=314(1.15)^x
NikAS [45]

Answer:

-10.76

Step-by-step explanation:

Let's solve your equation step-by-step.

4=314(1.5x)

Step 1: Flip the equation.

314(1.5x)=4

Step 2: Divide both sides by 314.

314(1.5x)/314

=

4/314

1.5x=2/157

Step 3: Solve Exponent.

1.5x=2/157

log(1.5x)=log(2/157)(Take log of both sides)

x*(log(1.5))=log(2/157)

x=

log(2/157)

log(1.5)

x=−10.760725

Answer:

x=−10.760725
