Write the equation for a parabola that has x − intercepts (−2.2, 0) and (−0.6, 0) and y − intercept (0,3.3). URGENT

Step-by-step explanation:

Given:

Parabola with

x − intercepts (−2.2, 0) and (−0.6, 0)

and

y − intercept (0,3.3)

To find:

Equation of parabola ?

Solution:

We can use factored form to find the equation of the parabola.

Where are the x intercepts.

Let use put

Now, let us put y − intercept (0,3.3) in the above equation to find the value of a.

So, the equation becomes:

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
