To solve the equation \( y^3 = 2x \) for \( y \), we need to isolate \( y \).
- First, take the cube root of both sides of the equation: \[ y = \sqrt[3]{2x} \]
This means \( y \) is equal to the cube root of \( 2x \).

For the second question about your texting habits, if you text 50 times every 2 days, you could represent the scenario with a linear function.
- You would find the rate of texts per day as: \[ \text{Rate} = \frac{50 \text{ texts}}{2 \text{ days}} = 25 \text{ texts per day} \]
If you want to express it in function form, assuming \( x \) is the number of days, the number of texts \( T \) you send can be expressed as: \[ T(x) = 25x \] for \( x \geq 0 \).
