Sketch the graph of the given function. The state the functions domain and rangef(x)=-2{1/4}^x​

Mathematics

Karolina [17]3 years ago

Answer:

Domain: -∞ < x < ∞

Range: f(x) < 0

Step-by-step explanation:

f(x)=-2(\frac{1}{4})^x

We need to sketch the graph and identify domain and range of the function f(x).

The graph is attached in the figure below.

Domain:

The domain of the function is all the values of x that gives the real values for f(x).

So, in our case all values of x gives real values for f(x). So domain is:

-∞ < x < ∞

Range:

The range of the function is the resulting f(x) values when we put all the values of x.

In our case the value of f(x) will always be less than zero because of the negative sign.

Range is:

f(x) < 0

Solve for www. Give an exact answer in simplified form. 53w+13 &lt; 56w + 16
ki77a [65]

The solution will be:  w>-1

<em><u>Explanation</u></em>

The given inequality is:   53w+13 < 56w + 16

First we will subtract 56w from both sides. So.....

53w+13-56w

Now we will subtract 13 from both sides. So.....

-3w

Then we need to divide both sides by -3. As here we are <u>dividing the inequality by a negative number, so we need to switch the inequality symbol</u>. So, we will get.......

\frac{-3w}{-3}>\frac{3}{-3}\\ \\ w>-1

Thus, the solution will be:  w>-1

Find the equation (in terms of x) of the line through the points (-2,1) and (3,5)
masha68 [24]

9514 1404 393

Answer:

  y = 4/5x +13/5

Step-by-step explanation:

The slope is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (5 -1)/(3 -(-2)) = 4/5

The y-intercept is given by the formula ...

  b = y -mx . . . . for any point (x, y)

  b = 1 -(4/5)(-2) = 1 +8/5 = 13/5 . . . . using the first point

So, the equation is ...

  y = mx +b

  y = 4/5x +13/5

<em>Additional comment</em>

If you have a bunch of these to do, you may want to make a spreadsheet with the formulas built in. Then you can type in the two points and have it spit out the m and b for your equation. Even if you don't use it to <em>do</em> the work, you can use it to <em>check</em> the work.
