No. If you invert that function, it will produce an equation that gives you two return values for one input value. This does not meet the definition of a function.

Is the inverse of the function y x2 still a function?
Y = 1/X2 ==============Can it pass the line test? * * * * * That is not the inverse, but the reciprocal. Not the same thing! The inverse is y = sqrt(x). Onless the range is resticted, the mapping is one-to-many and so not a function.
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.
What is the inverse of y x2?
Y = X2 Inverse. Y = 1/X2 ======
Is y equals x2 a function?
Y=X^2 is a function for it forms a parabola on a graph.
Is x2-y2 plus 49 equals 0 a function?
Yes

Which functions do not have an inverse?
y = x2 where the domain is the set of real numbers does not have an inverse, because the square root function is a one-two-two mapping (except at 0). Any polynomial with more than one root, over the reals, has no inverse. y = 1/x has no inverse across 0. But it is possible to define the domain so that each of these functions has an inverse. For example y = x2 where x is non-negative has the square root function as its inverse.
Is y equals x2 plus 1 a function?
Yes. Think of y as being a function of x. y = f(x) = x2 + 1
Is y equals x2 a function?
Y=X^2 is a function for it forms a parabola on a graph.
Is f9x0 equals x3-x2 plus 5 a linear function?
No, it is not.
Is x2-y2 plus 49 equals 0 a function?
Yes
What is the inverse of x squared minus four?
1 over x2 - 4 is the multiplicative inverse of x2 minus four 1/x2 - 4
What is Additive inverse of x2 yz is?
The additive inverse of x2yz is -x2yz
What is the implicit form and explicit of the function x2 plus 2y equals 5?
Implicit: x2 + 2y = 5 Explicit : y = (5 - x2)/2
What is the function for y equals x2?
f(x) = x2 This describes a parabolic curve, with it's vertex at the point (0, 0)
