Use the graph to determine the function's domain and range.

question 9 options:

domain: [0, ∞) range: (-∞, ∞)

domain: [0, ∞) range: [-1, ∞)

domain: (-∞, ∞) range: [-1, ∞)

domain: [0, ∞) range: [0, ∞)

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
