Devon is having difficulty determining if the relation given in an input-output table is a function.

Marco explains to him that in order to tell if the relation in the table is a function, Devon needs to check if any of the output values are repeated. If they repeat and have different input values, the relation is not a function.

Instructions:

Decide if you think Marco is correct or incorrect.
Answer the following depending on how you answered #1.
If you think Marco is correct, summarize Marco's reasoning in your own words.
If Marco is incorrect, explain what is wrong with Marco's reasoning and provide an example of a function.

What to submit:

3-4 sentences answering #2a or #2b depending if you agree or disagree with Marco.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
