Only if the domain (the numbers that you put into the function) are "bigger than or equal to zero". If the domain is "all real numbers",(i.e. including negatives) then it is not a one-to-one function. The question will tell you what the domain of the function (i.e. the values of 'x' that you are meant to input).

What is x2 minus 36 factorised?
x2 - 36 = x2 - 62 = (x + 6)(x - 6)
Which is a factor of x to the 2nd power minus 5x minus 6?
which of the following is a factor of x2 - 5x - 6
Quotient and remainder of 3X4 plus 2X3 minus X2 minus x minus 6 divided by X2 plus 1?
(3x4 + 2x3 - x2 - x - 6)/(x2 + 1)= 3x2 + 2x - 4 + (-3x - 2)/(x2 + 1)= 3x2 + 2x - 4 - (3x + 2)/(x2 + 1)where the quotient is 3x2 + 2x - 4 and the remainder is -(3x + 2).
Is y equals x2-4 a one to one function?
6
What is the factor x2 plus x minus 42?
(x + 7)(x - 6)
Can you solve x squared plus x minus six equals zero?
x2 + X -6 =0 so X2 + X = 6 so X2 = 6-x so X = square root of (6-x) That's as far as I can get it.
What is the polynomial of this factor x2 minus 9x plus 18 in descending order?
x2 - 9x + 18 = (x - 3)(x - 6)
What is 2x to the power of 6 minus 128?
2(x + 2)(x - 2)(x2 + 2x + 4)(x2 - 2x + 4)
How do you factor x2 plus 7x minus 6?
This is not factorable. You would have to do the quadratic formula for this problem.
What is x cubed minus 3x squared plus 6x minus 18 in simplest form?
(x - 3)(x^2 + 6)
How do you simplify x2-8x plus 12 will they both contain a minus sign?
Yes, both brackets will contain a minus sign. (x -2)(x-6)
If x is greater than 2 than x squared minus x minus 6 divided by x squared minus 4 equals?
x >2 x2 - x - 6/(x2 - 4) (x + 2)(x - 3)/(x + 2)(x - 2) cross out x + 2 (x - 3)/(x - 2) this is the most simplified this can be
