Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

What must be true for two figures to be congruent?
All of the angles between the sides need to be the same. The sides can be of any length, but because the angles are the same they will always be in the same ratio to each other.
Explain how to factorize 2x squared plus 7x plus 6?
Your equation is a trimonial (made up of 3 parts) so your equation will end up being two sets of parentheses. In the first parentheses at the beginning goes the 2x, and at the begining of the second parentheses is x (because when you multiply 2x by x you get 2x^2 (two x squared) next you need to find two numbers that multiply to get six and also when you add them together you get seven. However since the beginning number is 2 (from the 2x) one of those two numbers has to be multiplied by 2 in order to get seven. The numbers needed are 2 and 3 with the two being the one that is multiplied by two. Therefore the second two needs to be i the second paretheses and the three needs to be in the first. Your equation will end up looking like this:
(2x+3)(x+2)
What is the x-intercepts y equals 2x2 plus 2x - 4?
For the x intercepts, y = 0 ie 0 = 2x2 + 2x - 4
or x2 + x - 2 = 0 so that (x + 2)*(x - 1) = 0
So the intercepts are (-2,0) and (1,0)
What kind of symmetry indicates that a function will not have an inverse?
If a function is even ie if f(-x) = f(x). Such a function would be symmetric about the y-axis. So f(x) is a many-to-one function. The inverse mapping then is one-to-many which is not a function.
In fact, the function need not be symmetric about the y-axis. Symmetry about x=k (for any constant k) would also do.
Also, leaving aside the question of symmetry, the existence of an inverse depends on the domain over which the original function is defined. Thus, y = f(x) = x2 does not have an inverse if f is defined from the real numbers (R) to R. But if it is defined from (and to) the non-negative Reals there is an inverse - the square-root function.
What are 4 numbers added up to be -50?
We will assume you mean consecutive numbers. Algebraically, with X = numbers.
X +(X + 1) + (X + 2) + (X + 3) = - 50
4X + 6 = - 50
4X = - 56
X = - 14
X + 1 = - 13
X + 2 = - 12
X + 3 = - 11
(- 11, - 12, - 13, - 14 )

It is difficult to be certain, but since the question HAS been asked, I would hazard a guess and say that they are parallel. (If they weren't parallel, nobody would bother to ask!)

What are the domain and range of y equals ex plus 2 - 1?
I would suggest you plot it using, say GeoGebra. (Very easy to use.) On the left side of the y-axis the graph never falls below y=-1, I think. It climbs indefinitely on the right side. It extends indefinitely to the left, and to the right. But, as I say, if you learn GeoGebra, many problems like these will become much easier.

In any case, the solution for one linear equation, with two variables is an infinite set of points on the line that is defined by the equation.
How do you solve 3x squared plus x minus 14?
Do you mean: 3x2+x-14 = 0
If so the solutions are: x = 2 and x = -7/3 using the quadratic equation formula
4x = 3(x + 1) + 9
4x = 3x + 3 + 9
x = 12.
y = 13.
2x plus 4 plus 2x equals x plus 10?
2x+4+2x=x+10
add like terms
4x+4 = x+10
move x to the left hand side of the equation you have to take away x from
both sides (balancing method)
4x - x +4 = x-x+10
3x + 4 = 10
now move 4 to the right hand side
3x = 6
divide both sides by 3
x = 2
