Question

Which equation represents a function?A. x=13B. x-12=34C. 2y=-12D. 2x-4x=7E. x/2=15

Answer 1

Solution:

From the given equations,

A function must pass the vertical line test but, equations with only x as the variable will not pass the vertical line test.

From the explanation above;

The graph above will pass the vertical line test.

Hence, the equation represents a function is

$2y=-12$
