Select the correct answer.<br> Which function is the inverse of f(x) = -x^3 - 9?

joja [24]

Answer:

(2)

Step-by-step explanation:

Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)

Thus,

=> -x³ - 9 = y

=> - y - 9 = x³

=> (-y - 9)^(1/3) = x

=> f(y) = x

Inverse is (-y-9)^(1/3)

Replacing the variable, inverse is (-x-9)^(1/3)

Which is a solution to the equation |10-5y| = 20

kotegsom [21]

<u>Answer:</u>

The correct answer option is a) y =2.

<u>Step-by-step explanation:</u>

We are given the following equation and we are to find the solution of this equation:

$| 1 0 - 5 y | = 2 0$

Here, the expression $10-5y$ is given in a modulus, which means that its value cannot be negative.

$1 0 - 5 y = 2 0$

$-5 y = 2 0 - 1 0$

$-5 y = 1 0$

Ignoring the negative sign because of mod.

$y=\frac{10}{5}$

y = 2
