Is the function “ y = 3x “ a direct variation?

LuckyWell [14K]

Given function is a direct variation

Step-by-step explanation:

The direct proportion is defined as the increase in one quantity causes increase in other quantity.

If y is directly proportional to x, then it is given as:

y = kx

where k is the constant of proportionality

Given

y = 3x

Comparing the general form and given equation we see that both are same where k =3

So,

Given function is a direct variation

What is the range of this relation?

VARVARA [1.3K]

Answer:

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}

Step-by-step explanation:

{(2,4), (8,-3), (-5,-1), (4,6), (6,7), (9,0)}

The domain is the input and the range is the output

domain is { 2,8,-5,4,6,9} and the range is {4,-3,-1,6,7,0}

We put the numbers in order from smallest to largest

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}
