What is the equations for f(x)?

Wittaler [7]

$f(x) = -8\cdot 4^x$

You reflect a function with respect to the $x$ axis by changing its sign.

In fact, if you consider the two alternatives

$x \mapsto f(x)$ and $x \mapsto -f(x)$

you can see that you're choosing opposite outputs for the same inputs.

In other words, one graph will be made of points like $(x,f(x))$ , the other of points like $(x,-f(x))$

And the transformation

$(x,y) \to (x,-y)$

is exactly a reflection with respect to the $x$ axis.

If the parent function f(x)=\root(3)(x) is transformed to g(x)=\root(3)(x+2-4), which is the graph of g(x)?

Arisa [49]

ANSWER

EXPLANATION

The parent function is

$f(x) = \sqrt[3]{x}$

This function is transformed to obtain

$g(x) = \sqrt[3]{x + 2} - 4$

The +2 is a horizontal translation, that shifts the graph of the parent function to the left by 2 units.

The -4 is a vertical translation, that shifts the graph of the parent function down by 4 units.

The correct option is A.

If 0.142857142857......is expressed in the form m/n, then what is the value<br>of (2m + n)?

frosja888 [35]

Answer:

The value will be: 1,285,713

Step-by-step explanation:

We have the number:

N = 0.142857...

Such that we have 6 decimals after the decimal point that repeat infinitely.

Then let's start by multiplying our number by 1,000,000 (same number of zeros as decimals after the decimal point)

Then we get:

1,000,000*N = 142,857.142857...

Now let's subtract N from both sides:

1,000,000*N - N = 142,857.142857... - 0.142857...

999,999*N = 142,857

Now let's isolate N

N = 142,857/999,999

Here is our number expressed in the form m/n, where:

m = 142,857

n = 999,999

Then the value of (2*m + n) is:

(2*142,857 + 999,999) = 1,285,713

ILL GIVE BRAINLIEST ON THIS QUESTION!!!!!!!!!!!!!!!!!!!!!!!!!!!

DochEvi [55]

Answer:

15.25 or 15 if you need it to be rounded.

Step-by-step explanation:

-11 on both sides to get 5x=1x+61. Then, -1x on both sides to get 4x=61. Then to find x you do 61 divided by 4 which is 15.25.
