The graph of g(x) is obtained by reflecting the graph of f(x)=2|x| over the x-axis. which equation describes g(x)?
1. g(x)=|2x|
3. g(x)=−|x+2|
4. g(x)=|x+2|
5. g(x)=−|2x|

Step-by-step explanation:

Let's see the graph of the function f(x). According to the graph, we can see the next

Domain : R ( All real numbers)

Range : { x ∈ R : x ≥ 0}

If we reflecting f(x) over x-axis, the resulting function is the inverse of the function f (x), that is

, applying absolute value properties

  (I)

The graph of (I) is the second picture.

5. g(x) = −|2x|

Step-by-step explanation:

Given function,

Since, the reflection rule over x-axis is,

i.e. when a function f(x) is reflected over x axis, then the resultant function is -f(x),

Hence, if f(x) is reflected over x-axis to g(x),

Then,

g(x) = -f(x) = -2|x|

i.e. OPTION 5 is correct.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
