Help!!!!!!!!!!!!!!!!!!!!!!!
Nataly [62]
Hello.

Firstly, let's isolate x on the equation:

\mathsf{f(x) = 3x + 3} \\ \\ \mathsf{y = 3x + 3} \\ \\ \mathsf{-3x = -y + 3} \\ \\ \mathsf{x = \dfrac{-y + 3}{3}}

Now, we can replace 'x' for 'y' and vice-versa:

\mathsf{f^{-1}(x) = \frac{-x + 3}{3}`}

Hope I helped.

Twice "a" increased by the cube of "a" equals b.
MrRa [10]

Answer:

2a+a^3=b

Step-by-step explanation:

Let's do it part by part:

<u>Twice "a":</u>

This means 2 times a, or 2*a

<u>Cube of "a":</u>

This means a cubed, so a to the power 3, or a^3

Also note "is" means "equal" and "of" means "multiplication.

Twice a increased by cube of a means both parts are summed so we have:

2a+a^3=b\

This is the formula/equation
