Which equation represents the axis of symmetry of the function y=-2x² + 4x -6? Oy=1
Ox=1
Ox=3
Oy=3

B

Step-by-step explanation:

We are given the quadratic function:

And we want to find its axis of symmetry.

First, the axis of symmetry is always a vertical line. Hence, it should be represented by x. Thus, we can eliminate choices A and D.

Next, the axis of symmetry for a quadratic is always the x-coordinate of its vertex point. The vertex for a quadratic equation is given by:

For our function, a = -2, b = 4, and c= -6.

Therefore, our AOS is:

Hence, the equation of our axis of symmetry is x = 1.

B is our answer.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

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
