Question

the function g is defined by g(x)=|x + 12|. what is the value of g(3)? a -12 b -3 c 9 d 15

Explanation:

Step1: Substitute x = 3

Substitute x = 3 into g(x)=|x + 12|. We get g(3)=|3 + 12|.

Step2: Calculate the value inside the absolute - value

3+12 = 15, so g(3)=|15|.

Step3: Evaluate the absolute - value

The absolute value of 15 is 15, i.e., |15| = 15.

Answer:

D. 15
