Question

Which function is represented by the graph?

Answer 1

Answer:

The correct option is 2.

Step-by-step explanation:

The parent absolute function is

$f(x)=|x|$

The graph of this function is V-shaped and the vertex of this function is origin.

The transformation is defined as

$g(x)=|x+a|+b$                .... (1)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From the given graph it is clear that the function shifts 2.5 units up. It means a=0 and b=2.5.

Substitute a=0 and b=2.5 in equation (1).

$g(x)=|x+0|+2.5$

$g(x)=|x|+2.5$

The required function is g(x)=|x|+2.5. Therefore the correct option is 2.

Answer 2

The function is
g(x) = |x| + 2.5

the v shape comes from |x| shifted up from the origin by 2.5
