1. How to Solve using Algebra
Make both equations into "y =" format.
Set them equal to each other.
Simplify into "= 0" format (like a standard Quadratic Equation)
Solve the Quadratic Equation!
Use the linear equation to calculate matching "y" values, so we get (x,y) points as answers.
Algebraic method is more easy to do
2. linear functions have constant first differences. quadratic functions have constant second differences. exponential functions have a constant ratio.
