30 POINTS if f(x)=5x-6 and g(x)=x^2-4x-8, find (f+g)(x).

A. (f+g)(x) = x^2-9x-2
B. (f+g)(x) = 6x^2 - 4x - 14
C. (f+g)(x) = x^2 + x - 14
D. (f+g)(x) = x^2 - x -2

step-by-step explanation:

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
