Answer:
3
Step-by-step explanation:
Apparently, the coefficient of the absolute value is the "a" of interest. It is 3.
The standard form of an absolute value function is g(x)=a|x-h|+k
So, the value of a when the function f(x)=3|x| is written in the standard form of an absolute value function is 3 and the values of h and k are equal to zero.
