How do you solve X9 - Y6 equals X3 - Y2 Between each X and Y power is an exponent?
2x2-y2
Is this a function x equals y2?
Yes, as x-y2=0
What is the solution- Algebraic Fractions with Exponents where the answer is a half?
x4 / 2x4 396(x2 + y2) / 396(2x2 + 2y2)
Is y equals 2x2 a function?
no
Does every function have an inverse that is a function?
No. A simple example of this is y = x2; the inverse is x = y2, which is not a function.
How do you find the slope of a function?
Need two points. m = slope. (X1, Y1) and (X2, Y2) m = Y2 - Y1/X2 - X1 ==============Or, if function is in this form...... Y =mX + b ======== Read off of function, or get function is this form.
Is y2 equals x a function?
Y2 = Xtake square root each sideY = (+/-) sqrt(X)=============now it is a function as both these equation pass the vertical line test
Is y equals 3x plus 1 and -2x2 a function?
No.
Is x2-y2 plus 49 equals 0 a function?
Yes
What is an example of an algebraic rule that is not a function?
x2 - y2 = (x + y)(x - y) is an identity, not a function.
What quadratic function would be used to solve -2x2 plus 9x equals 12?
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
Is y2 equals x2 a function?
No, because there is more than one solution: y2 = x2 y = ±(x2)1/2 y = ±x Because there are multiple solutions for a single value of x, this does not qualify as a function.
