This equation describes a parabola, so it's range on the x-axis will be infinite. To find it's vertex, we can take it's derivative and solve for zero:

y = x2 + 4

y' = 2x

Let y' = 0

0 = 2x

x = 0

Now we plug that x value into the original equation to find y:

y = 02 + 4

y = 4

So the vertex is at the point (0, 4). To see whether that's a minimum or a maximum, we need only take it's second derivative and check whether it's positive or negative at that point:

y' = 2x

y'' = 2

So the rate of change of the slope is positive, which means that the parabola's vertex is a minimum. We can say then that the equation has an infinite x range, and a y range from 4 to infinity.

A body moving with constant speed in a circular path has acceleration changing at every point.

Stochastic testing is the same as "monkey testing", but stochastic testing is a lot more technical sounding name for the same testing process.

Stochastic testing is black box testing, random testing, performed by automated testing tools. Stochastic testing is a series of random tests over time. The software under test typically passes the individual tests, but our goal is to see if it can pass a large number of individual tests.

Without knowing the value of x and the required unit of length then a meaningful answer to this question cannot be provided.

x = 3

It's negative 2.

First, factorise both numerator and denominator:

(2x - 4) / (x2 - 4)

= 2(x - 2) / (x + 2)(x - 2)

= 2 / (x + 2).

I suspect the answer is yes, but it all depends on the exact form of the equation.

For example, y = ax2 + bx + c (the equation of a parabola).

Every parabola has an axis of symmetry and the graph to either side of the axis of symmetry is a mirror image of the other side. It means that if we know a point on one side of the parabola, we can find its symmetric point to the other side, based on the axis of symmetry. Those symmetric points have opposite x-coordinate values, and the same y-coordinate value. The vertex only is a single point which lies on the axis of symmetry.

The equation for the force of gravity is F=-GMm/r2 at the equator the earth has more mass due to the gravity of the sun distroting the sherical shape of the earth. But this mean that the distance between the centre of the earth to the poles (r) is less and because r is squared the effect of distance has more of an impact than the mass so this means that gravity is stronger at the poles and weaker at the equator.....

Simply substitute a 3 in for y. 2(3) + 3 = 6 + 3 = 9.

Note: If this question is from work you have been assigned by a teacher or professor, I suggest you do the work yourself instead of trying to find the answers online. This will help you to better understand the material and become more familiar with it. Of course, if this question was not from homework, you can ignore this message.

4 X 2.5 = 10

(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3)

= 2x3 + 6xy2 = 2x*(x2 + 3y2)
