Question

Determine if the following equations are functions. Assume y is the dependent variable write "yes" or "no".

Answer 1

Determine if the following equations are functions. Assume y is the dependent variable write "yes" or "no".

y=3x^2__
3(x^2+y^2)=1__
3=4x^2+2xy-7___
(y-2)^2+4x=1___

4x^3-2y=16___
y^3=x-1___
x=3y^2___
2x+2y=7___

Answer 2

you can tell if something is a function by plugging in x (input) values

if two different input values have the same y (output) values, the equation is not a function
