Question

evaluating functions
the graph of the function ( k(x) ) is shown below. use the graph to answer the following questions.
evaluate ( k(2) ):
( k(2) = )
for what value(s) of ( x ) does ( k(x) = 2 )?
( x = )

Explanation:

Step1: Find k(2) from graph

Locate $x=2$ on the x-axis, move up to the line, the y-value is 4. So $k(2)=4$.

Step2: Find x for k(x)=2

Locate $y=2$ on the y-axis, move right to the line, the x-value is -3. So $x=-3$.

Answer:

$k(2)=4$
$x=-3$
