Find the zero of the function below:
f(x) = 4x + 12

x = - 3

Step-by-step explanation:

To find the zero, let f(x) = 0, that is

4x + 12 = 0 ( subtract 12 from both sides )

4x = - 12 ( divide both sides by 4 )

x = - 3 ← is the zero

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
