Use the graph below to answer this question.
find the average rate of change for the given function from x = -3 to x = 1

Rate of Change is 1

Step-by-step explanation:

The Average rate of change is the ratio of change in y and the change in x

Hence

Avg Rate of Change  = Change in y / Change in x

The two coordinates are

(-4,0) and (0,4)

Change in x = 0-(-4) = 4

Change in y = 4-0 = 4

Hence

Avg Rate of Change = 4/4

= 1

Answer = 1

step-by-step explanation:

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
