Muy bien. Nos fijamos que el punto <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mo»(«/mo»«mn»0«/mn»«mo»,«/mo»«mi»#b«/mi»«mo»)«/mo»«/math»</span> pertenece a la recta. <br />

Atención, has confundido imagen y antiimagen. Los puntos <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mo»(«/mo»«mn»0«/mn»«mo»,«/mo»«mi»#b«/mi»«mo»)«/mo»«/math»</span> y <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mo»(«/mo»«mi»#e«/mi»«mo»,«/mo»«mn»0«/mn»«mo»)«/mo»«/math»</span> pertenecen a la recta, pero el segundo punto nos indica que la antiimagen del 0 es #e.
Choice 3
Answer
La gráfica de la función f(x)=#g es paralela a la gráfica dada

Atención, f(x) no tiene el mismo pendiente que la recta de la gráfica dada. El pendiente es el opuesto al de la recta de la gráfica. <br />#q<br />
Choice 4
Answer

Muy bien. La ordenada al origen es #b, entonces, la recta corta el eje de ordenadas en <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mo»(«/mo»«mn»0«/mn»«mo»,«/mo»«mi»#b«/mi»«mo»)«/mo»«/math»</span> <br />#q<br />
