Describe how to transform the graph of g(x)= ln x into the graph of f(x)= ln (3-x) -2.
Strike441 [17]

Answer:

The graph of g(x) = ㏑x translated 3 units to the right and then reflected

about the y-axis and then translated 2 units down to form the graph of

f(x) = ㏑(3 - x) - 2

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

 function g(x) = f(-x)

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* lets solve the problem

∵ Graph of g(x) = ㏑x is transformed into graph of f(x) = ㏑(3 - x) - 2

- ㏑x becomes ㏑(3 - x)

∵ ㏑(3 - x) = ㏑(-x + 3)

- Take (-) as a common factor

∴ ㏑(-x + 3) = ㏑[-(x - 3)]

∵ x changed to x - 3

∴ The function g(x) translated 3 units to the right

∵ There is (-) out the bracket (x - 3) that means we change the sign

  of x then we will reflect the function about the y-axis

∴ g(x) translated 3 units to the right and then reflected about the

   y-axis

∵ g(x) changed to f(x) = ㏑(3 - x) - 2

∵ We subtract 2 from g(x) after horizontal translation and reflection

  about y-axis

∴ We translate g(x) 2 units down

∴ g(x) translated 3 units to the right and then reflected about the

   y-axis and then translated 2 units down

* The graph of g(x) = ㏑x translated 3 units to the right and then

  reflected about the y-axis and then translated 2 units down to

  form the graph of f(x) = ㏑(3 - x) - 2

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?
USPshnik [31]
\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ &#10; \frac{x}{2 \pi } + \frac{1-x}{2} = 0
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π    / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )

Write an equation that relates the number of peppers, n, and the<br><br> cost, C.
SCORPION-xisa [38]

Complete Question:

The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the  cost, C.

Answer:

C = 0.45n

Step-by-step explanation:

Given

5\ peppers = \$2.25

Required

Determine the relationship between C and n

5\ peppers = \$2.25

Divide both sides by 5, to get the cost of 1 pepper

\frac{5\ peppers}{5} = \frac{\$2.25}{5}

1\ pepper = \frac{\$2.25}{5}

1\ pepper = \$0.45

Multiply both sides by n to get the cost of n pepper

n*1\ pepper = \$0.45*n

n\ pepper = \$0.45n

So, we have:

C = 0.45n
