Identify the initial amount a and the growth factor b in the exponential function.

alina1380 [7]

Given the equation A (x) = 30 x 8.3 ^x, we can get the initial amount of A when x is equal to zero. Therefore:

A (0) = 30 * 8.3^0

A (0) = 30

In this case the equation grows by 8.3 times as x increases. Therefore the growth factor is 8.3.

Answers:

initial amount = 30

growth factor = 8.3

The answers are not in the given choices. I believe you are giving the wrong equation. If the correct equation here is:

A (x) = 680 x 4.3 ^x

Then the answers are:

initial amount = 680

growth factor = 4.3

The answers are now in the choices given.

Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is ____. (Input numb

You could graph this, but it is simpler in this case to do it mathematically.

Since the x and values are the same (implying undefined slope) you can subtract the smaller y value from the larger y value. 2.5-1.2=1.3.

The graph first represents the provided piecewise function option first is correct.

<h3>What is a piecewise function?</h3>

The graph of a piecewise function contains numerous curve components. It signifies that it has a plethora of definitions based on the value of the input. In other words, a piecewise function behaves differently depending on the input.

We have a piecewise function shown in the picture.

$\rm y=\left\{x\le-2:\sqrt{-x-2}\right\}$

$\rm y=\left\{-2 < x < 1:\dfrac{x}{x^{2}+x-2}\right\}$

$\rm y=\left\{x\ge1:\log_{2}\left(x+1\right)\right\}$

After plotting all the pieces of a function on the coordinate plane we will get a graph the same as shown in the first option.

Thus, the graph first represents the provided piecewise function option first is correct.
