Answer 1

A relation is a function if for each value of x (input value) there is a unique value of y (output value). For the equation given in the problem:

y= |x| +4

There is a unique value of y for each value of x.

Therefore, the equation is a function and a function is also a relation.

Then, the answer is option A.
