<h3><u>Answer:</u></h3>

Hence, the multiplicative Rate of change is:

<h3><u>Step-by-step explanation:</u></h3>

The multiplicative Rate of change refers to the fixed constant which when multiplied to the output will lead to increase/decrease in the next output value.

We have the table of values as:

x y

-1 1/10

0 1/2

1 5/2

2 25/2

3 125/2

Hence, we see that when 5 is multiplied to the output value we obtain the next output value.

i.e.

1/10×5=1/2

1/2×5=5/2

5/2×5=25/2

25/2×5=125/2

Hence, the multiplicative Rate of change is:

Answer:

$y = 30x+290$

Step-by-step explanation:

Given

$y=-x^2+65x+256$

Required

The linear function of a competitor's website

On day 1, both websites have the same subscribers.

This implies that:

$y=-x^2+65x+256$

Substitute: $x =1$

$y=-(1)^2+65*1+256$

$y=-1+65+256$

$y=320$

This implies:

$(x_1,y_1) = (1,320)$

On day 34, both websites have the same subscribers.

This implies that:

$y=-x^2+65x+256$

Substitute: $x =34$

$y=-(34)^2+65*34+256$

$y=-1156+2210+256$

$y=1310$

This implies:

$(x_2,y_2) = (34,1310)$

To calculate the linear function of the competitor, we have:

$(x_1,y_1) = (1,320)$

$(x_2,y_2) = (34,1310)$

Calculate slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

$m = \frac{1310 - 320}{34-1}$

$m = \frac{990}{33}$

$m = 30$

The equation is then calculated as:

$y = m(x - x_1) + y_1$

This gives:

$y = 30 * (x - 1) + 320$

Open bracket

$y = 30x - 30 + 320$

<em></em> $y = 30x+290$ <em> --- This represents the linear function of the competitor's website</em>
