Which equation is represented by the graph?

A.) f(x)= -|x+8|
B.) f(x)= -|x|-8
C.) f(x)= |x+8|
D.) f(x)= |x-8|

Answer 1

The graph that you see below is C. f(x)= |x+8|

To find this, we first know we need a positive front number. We know this since the graph points up. As a result, we know the answer is either C or D.

Now to determine which is correct, use the point (-8, 0) represented on the graph to see if it belongs on the graphs for C or D. Whichever it works for is the correct answer. Below is the work for C.

f(x)= |x+8|

0= |-8+8|

0= |0|

0 = 0 TRUE

Therefore c is the correct answer
