The function y = 2x represents a linear function with a constant rate of change of 2. It means that for each unit increase in x, there will be a corresponding increase of 2 units in y.
The surface area (SA) formula depends on the specific shape or object for which you want to calculate the surface area. Here are some common surface area formulas for basic shapes:
- Rectangular prism: SA = 2lw + 2lh + 2wh (where l is the length, w is the width, and h is the height)
- Cube: SA = 6s^2 (where s is the length of each side)
- Sphere: SA = 4πr^2 (where r is the radius)
- Cylinder: SA = 2πrh + 2πr^2 (where r is the radius and h is the height)
