Identify the dependent variable as either increasing, decreasing, or unchanged as the independent variable increases. It is possible to have no relationship shown on the graph.

Depending on which way the scattered points go. If it goes up to the right it is positive or down to the left is negative. If the points are all willy-nilly then there is no coloration.

A population of caribou in a forest grows at a rate of 3% every year. If there are currently 208 caribou, which function represe

Answer:

f(x)=208^0.3x

Step-by-step explanation:

Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.

The generic formula fr an exponential equation is a^x.

A represents your initial value. In this case, its 208

x represents the growth. In this case, it's 0.3%.

Your equation should be f(x)=208^0.3x

What is the solution set of 2x(x - 1) = 3?

garik1379 [7]

First you must distribute the 2x to the numbers inside the parentheses

(2x * x) + (2x * -1) = 3

$2x^{2}$ - 2x = 3

To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides

$2x^{2}$ - 2x - 3 = 0

Use the quadratic equation to solve this (image of the quadratic equation is below)

Remember that quadratic functions are set up like so:

$ax^{2} +bx +c = 0$

That means that in this equation...

a = 2

b = -2

c = -3

^^^Plug these numbers into the quadratic equation and solve...

$\frac{2+/-\sqrt{(-2)^{2}-4(2)(-3)}}{2(2)}$

$\frac{2 +/-\sqrt{4+24}}{4}$

$\frac{2+/-\sqrt{28} }{4}$

$\frac{2+/-2\sqrt{7} }{4}$

$\frac{1+/-\sqrt{7} }{2}$

Keep in mind that +/- is ±

$\frac{1+\sqrt{7} }{2}$

$\frac{1-\sqrt{7} }{2}$
