Determine f –1(x) if f of x is equal to the quantity x plus 3 end quantity over the quantity x minus 4 end quantity where x 4.
f inverse of x is equal to the quantity x minus 1 end quantity over the quantity 4 times x plus 3 end quantity
f inverse of x is equal to the quantity 4 times x plus 3 end quantity over the quantity x minus 1 end quantity
f inverse of x is equal to the quantity x minus 4 end quantity over the quantity x plus 3 end quantity
f inverse of x is equal to the quantity x minus 3 end quantity over the quantity x plus 4 end quantity

Answers

Answer:

Option B

Step-by-step explanation:

Given function:

f(x) = (x + 3)/(x - 4)

Find its inverse, take f(x) as y and swap x with y

x = (y + 3)/(y - 4)x = (y - 4 + 7) / (y - 4)x = 1 + 7/(y - 4)x - 1 = 7 / (y - 4)y - 4 = 7 / (x - 1)y = 4 + 7 / (x - 1)y = (4x - 4 + 7)/ (x - 1)y = (4x + 3) / (x - 1)

Replace y with f⁻¹(x):

f⁻¹(x) = (4x + 3) / (x - 1)

Correct choice is B

A x is equal to the quantity x plus 3 end quantity over the quantity x minus 4 end quantity where x 4. at x = 0.5, the inverse function f²(-1)(x) f²(-1)(x) = 0.5

To determine the inverse of the function f(x) = (x + 3) / (x - 4), to follow these steps:

Replace f(x) with -1, since you're looking for the inverse at the point where f(x) = -1:

-1 = (x + 3) / (x - 4)

Solve for x in terms of -1:

Multiply both sides by (x - 4):

-1 ×(x - 4) = x + 3

Distribute the -1:

-x + 4 = x + 3

Solve for x:

Subtract x from both sides:

4 = 2x + 3

Subtract 3 from both sides:

1 = 2x

Divide by 2:

x = 0.5
