Question

determine whether the equation (16x^2-y^2=0) represents y as a function of x

Answer 1

try solving it for y

Answer 2

16x^2 - y^2 = 0

16x^2 = y^2 , now take the square root of both sides

Answer 3

take the square root of both sides

Answer 4

I still don't get it

Answer 5

after taking the square root of both sides, you end up with

4x = y , do you know what kind of graph this would make?

Answer 6

do you have a graph calc?

Answer 7

y = 4x is a linear function....

Answer 8

does this make it not a function of x then?

Answer 9

yep
