Which direction do we shade for -3 < x ?
A que lado coloreas para la desigualdad -3 < x ?
Right (mirror it/flip it to have x on the left side)

Is the following inequality graphed correctly? Explain
La desigualdad esta graficada correctamente? Explica
x < 6
No, it should be shaded to the left side with an open circle. The graph shows x ≥ -6
No, debe de ser coloreada hacia la izquierda con un circulo abierto. La grafica demuestra x ≥ -6
400
If graphing x < 5, we would put an open circle on 5 and shade to the right.
Si graficando x < 5, pondriamos un circulo abierto en el 5 y coloreamos hacia la derecha.
False
