Select a correct answer.

What is the range of the function shown on the graph above?
A. -7≤y≤-2
B.-8≤y≤8
C.-2≤y≤-7
D. -9≤y≤8

The range of a graph is the possible y-values, the graph can take.

The range of the function is (D) -9≤y≤8

From the graph, we have the following observations.

So, the range of the function is: [-9, 8]

This can be rewritten as: -9≤y≤8

Hence, the range of the function is (D) -9≤y≤8

D. -9≤y≤8

Step-by-step explanation:

Range is the set of all outputs (y-values)

From the graph, the least y value is -9 and the greatest is 8

Range: -9≤y≤8

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
