Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=8800(0.93)^x

y= 16(0.25)^x

The exponential equation represents an exponential decay because the rate of decay is 0.25 which is less than 1.

The general form equation is:

y(x)= a(1-r)^x such that r is the decay percent.

Comparing two equation we have 1-r = 0.25

==> r= 1-0.25 = 0.75 = 75%

2. y= 0.8(1.8)^x

The equation represents exponential growth because the growth factor is greater than 1.

==> 1+r = 1.8

==> r= 0.8 = 80%

Then, the growth percent is 80%

3. y= 17(1/5)^x

The equation represents exponential decay because 1/5 is less than 1.

==> 1-r = 1/5

==> r= 1- 1/5 = 4/5 = 0.8= 80%

go on the tube you might find some information there

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
