1

3

Answer 1

3

Explanation:

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.

Answer 2

3

Explanation:

Apparently, the coefficient of the absolute value is the "a" of interest. It is 3.
