How does making "a" negative change the direction of the graph?

Replace "x" with all of the x values in the graph each time to create the "y" coordinate.

Sustituye 'x' con todos los valores de x en el gráfico cada vez para crear la coordenada 'y'.

Graph f(x) = x²

​(-2)² = -2 x -2 = 4

​(-1)² = -1 x -1 = 1
