which of the following is the value of a when the function (f(x)=3|x|) is written in the standard form of an absolute - value function?\n-1\n-3\n1\n3
Answer
Explanation:
Step1: Recall standard form
The standard form of an absolute - value function is (y = a|x - h|+k). For the function (f(x)=3|x|), it can be written as (f(x)=3|x - 0|+0).
Step2: Identify the value of (a)
Comparing (f(x)=3|x - 0|+0) with (y = a|x - h|+k), we can see that (a = 3).
