Question

1. for the graph at left, what is the range? your answer is in the format of

umber< / ≤ y < / ≤number\

Explanation:

Step1: Identify minimum and maximum y - values

The lowest point on the graph in the y - direction is around $y = - 10$ and the highest point is around $y = 10$.

Step2: Determine range notation

The range includes all the y - values between the minimum and maximum. Since the graph has solid endpoints (assuming from the way the line segments are drawn), we use $\leq$.

Answer:

$-10\leq y\leq10$
