Step-by-step explanation:
<u>Step 1: Make a system of equations</u>
The easiest place to place the parabolas are at the origin or (0, 0). So, the parabolas are going to have an equation similar to y = x^2. The line that crosses the same vertex of the 2 parabolas is going to be y = 0 because both of the parabolas vertex is going to be at (0, 0).
y = 0 is the line
y = x^2 is one of the parabolas
y = 2x^2 is another one of the parabolas
