The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have the slope m = -2 and y-intercept (0, 3) → b = 3. Substitute:

What is the multiplicative rate of change for the exponential function graphed to the left?

schepotkina [342]

Answer:

The multiplicative rate of change is 3

Step-by-step explanation:

The given graph passes through the points:

$(-2,\frac{2}{9}),(-1,\frac{2}{3}),(0,2),(1,6),(2,18),(3,54)$

The multiplicative rate of change is the factor that multiplies each y-value to give the subsequent y-values.

We can find that factor by dividing a y-value by the previous y-value of any two consecutive y-value.

The multiplicative rate of change is $\frac{6}{2}=3$ or $\frac{18}{6}=3$ or $\frac{54}{18}=3$ or $\frac{2}{\frac{2}{3} } =3$ .

Take some time to fill in your notes, the area that is not shown in this video. Fill in the table with the values you think are

joja [24]

The x-values are the heartbeat(s) and the y-values are the time(s)

<h3>How to determine the x and y values?</h3>

The variables are given as:

Time(s) and Heartbeat(s)

As a general rule, the action that is being done is the independent variable.

The action here is the heartbeat.

So, the x-values are the heartbeat(s) and the y-values are the time(s)

A possible value of this is;

x = 100, y = 60 seconds

So, the ordered pair is (100,60)

When represented as ratio, we have;

Ratio = 60/100

Simplify

Ratio = 0.6 heartbeat per second
