Answer:
The most basic quadratic function is y = x2. This is also called the parent function of a quadratic function. Sometimes you will see it written in function notation as f(x) = x2. The graph of y = x2 looks like the graph below.
|5x+15|=10x
5x+15=10x 5x+15=-10x
-5x -5x -5x -5x
15=5x 15=-15x
divide by 5 divide by -15
3=x -1=x
