Given the function f(x) = -|x+5| + 12 on your graphing calculator, what is the most appropriate viewing window to see the graph?

a.)Xmin: –10, Xmax: 10
Ymin: –10, Ymax: 10

b.) Xmin: –20, Xmax: 20
Ymin: –20, Ymax: 20

c.) Xmin: –5, Xmax: 5
Ymin: –20, Ymax: 20

d.) Xmin: –10, Xmax: 10
Ymin: –5, Ymax: 5

Respuesta :

B) would be the most appropriate viewing window.

The graph of this function is shifted up 12 units from the parent graph; thus we need our y-value to go up past 10.  This eliminates a and d.

The graph is also shifted to the right 5 units.  This means we need to go past 5 on the x-axis to see the entire graph.  This eliminates choice c, leaving us with b.

Answer: B

Step-by-step explanation: Xmin: –20, Xmax: 20

Ymin: –20, Ymax: 20
