F (x) = – x2 + 4x + 1
g(x) = x + 1
What are the solutions to the equation f(x) = g(x)?
Select each correct answer.

x = 0 or x = 3

Step-by-step explanation:

if f(x) = g(x) then – x2 + 4x + 1 = x + 1

add the like terms

-x^2 +3x = 0

-x (x-3) = 0 then x is either 0 or 3

The 2 solutions are 0 and 3,

Step-by-step explanation:

– x2 + 4x + 1 = x + 1

-x^2 + 3x = 0

x(-x - 3)

x = 0 or -x - 3 = 0  which gives x = 3.

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
