How do you determine if the graph of a quadratic function has a min or max from its equation?
If x2 is negative it will have a maximum value If x2 is positive it will have a minimum value
The absolute value for x2?
As long as the range of values for x stays within the set of real numbers, then:|x2| = x2As the square of a real number will always be positive anyway.If on the other hand, x belongs to the set of imaginary numbers, then:|x2| = -x2The reason for that is that in the case of imaginary numbers, x2 will give you a negative number. Its absolute value then would be the negative of that.And with complex numbers it's, well... complex:(ai + b)2 = -a2 + 2abi + b2So:|(ai + b)2| = a2 + 2abi + b2
Is the value of 2x always smaller than the value of x2?
No. For 0 < x < 2, 2x is larger.
If a function is negative at a test number it will reach zero before it reaches an asymptote?
Not necessarily. f(x) = -1-x2 is negative for any test value of x, it is asymptotically negative infinity, but it is NEVER zero.
What is the square root of -x squared?
-x times -x = x2 (negative multiplied with negative = positive) sqrt of x2 = x

What does x2 - x2 equal to?

What is the answer for this 9 equals x2 plus 57?
This equation is unsolvable as x2 cannot be a negative number as would be suggested by this equation. Any number, even a negative, multiplied by itself will always give a positive number but this equation leaves you with x2 = -48

What is the value of X2 plus X?
The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.
What are the solutions to x2-10x 250?
The Answer to x2-10x250 is negative 2500, also -2500.
When a variable is on top and there is a line between the other variable is it division?
no, its subtraction. if x2 is over x to the first power, the exponent at the higher value subtracts the x1. whether the x2 is above or below x1, x1 is always being subtrated from x2. X2 X(1) x __ OR __ = X or _ X(1) X2 1
What is the solution to x squared minus 42 equals negative x?
It is a quadratic equation and the value of x is -7 or 6 x2 - 42 = (-x) x2 + x - 42 = 0 (x + 7) (x - 6) = 0
How do you simplify mathematical expressions with negative and zero exponents?
Any value to the zero power is 1. If an exponent is negative, you need to switch it from the numerator to the denominator or vice-versa. For example, x-2 is 1/x2.
