the graph of the function f(x) = x^3 – 7x – 6 intersects the x-axis at the points (–2, 0), (–1, 0), and (3, 0) as shown.

which expression is equivalent to x^3 – 7x – 6?

  D) (x + 1)(x + 2)(x - 3)

Step-by-step explanation:

The x-intercepts are given as x = -2, x = -1, and x = 3

x = -2 -->   x + 2 = 0

x = -1  -->   x + 1 = 0

x =  3 -->   x - 3 = 0

The factors of the equation are:    (x + 2)(x + 1)(x - 3) = 0

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

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
