Answer:
Nico's solution is correct
Step-by-step explanation:
Lorena introduced a spurious minus sign in the denominator in the next-to-last step, so ended up with a result that has the wrong sign.
Using symmetry concepts, it is found that there is a line of symmetry at x = 50, option D.
- A line symmetry is an imaginary line that runs through a graph, dividing it into two equal parts.
- A point symmetry is when every point is equidistant to the line of symmetry, but in opposite directions.
- In this problem, the values of x range from 0 to 100, being divided(definition changed) at 50, thus, there is a line of symmetry at x = 50, and option D is the correct one.
