It is x-3 and the value of that expression depends on the value of x. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

Y equals x3 plus 4x - 3.6?

IMPOSSIBLE


How does the shape of y equals x2 differs from the graph of y equals x3?

y = x2 is an (approximately) U shaped graph that is entirely above the x axis and is symmetric about the y axis. y = x3 is asymptotically negatively infinite when x is negatively infinite and positively infinite when x is positively infinite. It is symmetric about the line x+y=0.


An equation of the line tangent to the graph of y equals x3 plus 3x2 plus 2 at its point of inflection is?

What is the derivative of x3-8?

Let y = x3 - 8, then y' = 3x2 + 0 = 3x2.


What is the value of 2x3 plus 15y if x equals -7 and y equals 2?

If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656


What is the direct variation equation for x3 y2?

y = kx3/2If y2 varies directly with x3, then y varies directly with sqrt(x3) or x3/2.Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. If your question is not answered, please resubmit it, spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (x^2) or x-squared. :-)


Is y equals -x cubed plus 1 a function?

Yes, y = -x3+1 is a function. You can graph it and see that it passes the vertical line test. See related link, below.


How do you factor x to the sixth minus y to the sixth?

x6 - y6 = (x3)2 - (y3)2 = (x3 + y3) (x3 - y3) = (x + y)(x2 - xy + y2)(x - y)(x2 + xy + y2)
