Thusx^2+y^2=9doesn ot define y as a function of x.Consider the equation x2+y2=9. Solvin 9x^2+y^2=9foryyields y^2=9-x^2 y=±√(9-x^2) Because the right hand side ±V9-x2 produces two values of y for each value of x for example when x = 0, y = 3 or y = -...
We can write the function as f(x)=x^2+ 2. (2)We try to solve for y in terms of x:x^2+y^2= 4y^2= 4-x^2 Subtract x^2y=± √(4-x^2) Take square rootsThe last equation gives two values of y for a given value of x. Thus, the equation does not define y a...
Answer to: Determine whether the equation defines y as a function of x. x^2 + 3y = 2 a. Function b. Not a function By signing up, you'll get...

F(x,y,z)=0 is assumed to define z as a function of x and y, that is, z=f(x,y). So by (7), (∂ z)(∂ x)=- (F_x)(F_z) since F_z≠ 0.Similarly, it is assumed that F(x,y,z)=0 defines x as a function of y and z, that is x=h(x,z). Then F(h(y...
The same can be done with groups to define polynomials over a group G. Now the problem \(\textsc {{PolSat}} \!\left ({G} \right )\) takes as input an equation of the form t(x1,…,xn) = s(x1,…,xn) (or equivalently t(x1,…,xn) = 1, by replacing t = s by ts−...
Does the equation x^{2} + y^{2} = 100 define y as a function of x? does the equation x^2+y=121 define y as a function of x? Does the equation x^2 + y=64 define y as a function of x. a) Yes b) No Does the equation define y as a function of x? y = 9x^{2} ...
Determine whether the equation definesyas a function ofx. x2+y2=1. Function A function is an equation that takes an input and gives out an output. This output is dependent on the input and there can be only one output for an input. For example,y=f(x)=nx, then the v...
We usez=g(x,y)to represent surfaceS, wheregis a function of x and y. We defineG(x,y,z)=z-g(x,y). Its unit normal vectornequals: Therefore, using (10) and (14), equation (12) can be written as: This is the formula for a surface to be projected on thex-y surface. There...
