Plot the function. y= (x+1)(x-3) by following these steps : plot the x-intercepts of the function

Step 1: Plot the x-intercepts of the function. (-1,0) and (3,0)

Step 2: Plot the point on the x-axis that is half way between the intercepts. (1,0)

Step 3: Plot the vertex on the dashed line. (1,-4)

Step 4: Plot the y-intercept. (0,-3)

Step 5: Use symmetry to plot another point where y= -3. (2,-3)

Step 6: The smooth curve through these points shows the graph of the function. --there is no answer for this step but the graph has points plotted from left to right are (-1,0), (0,-3), (1,-4), (2,-3), and (3,0)

correct answer:

b.(19,-2)

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
