The rule is x→y=−x. Can you mark all the points that fit the rule on a coordinate plane?

(x, -1)

Step-by-step explanation:

The arrow is an operator.

It means that if you take some point (x,y) and then do x -> y, you get -x.

So think, what are ways to change x to -x? Multiplying by -1. So x -> y can be viewed as the same as the function g(x) = x * (-1) = -x.

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
