What is the inverse function of f(x) = 19/x^3

erica [24]

Answer:

Step-by-step explanation:

1) Replace f(x) with y: y = 19/x^3

2) Interchange x and y: x = 19/y^3

3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or

y = ∛[19/x]

-1

4. Replace this y with the label f (x) = ∛[19/x]

Solve the system of equations below x-2y=3 2y-3y=9

Crank

First you solve 2y-3y=9.
$2y - 3y = 9 \\ subtract \: 2y \: and \: 3y \\ - y = 9 \\ divide \: by \: - 1 \\ y = - 9$
Now that you have y, then you substitute y into x-2y=3 to find X

$x - 2( - 9) = 3 \\ multiply \: - 9 \times - 2 \\ x + 18 = 3 \\ subtract \: 18 \: on \: both \: sides \\ x = - 15$
Your solution is (-15, -9)
