Question

Determine whether the equation defines y as a function of x: y^2+x=4

Answer 1

what does your question mean?

Answer 2

This is a question on my homework. It just says determine whether the equation defines y as a function of x and then gives that equation.

Answer 3

what does it mean?
what is a function, what makes it a function of x?

Answer 4

a function is a relation that associates with each element of x exactly one element of y. I have no idea what makes it a function or if it is a function.

Answer 5

you did not define it in your own words?

Answer 6

f(x) = dog
y = dog

Answer 7

Help!!

Answer 8

does not define y as a function of x, because some value(s) of x have more than one y.

Answer 9

You're done.

Answer 10

Thanks!

Answer 11

You can solve it algebraically as well, and you'll still see y has more than 2 x values so it's not defined.

Answer 12

how would you do it algebraically to show work?
