Answer:
k(- 1) = 7
Step-by-step explanation:
Locate x = - 1 on the x- axis, go vertically up to meet the graph at (- 1, 7 )
then when x = - 1 , y = 7 , that is
k(- 1 ) = 7
Based on the graph, the value of k(-1) is 7. meaning that when -1 is the input, 7 is the output.
Therefore, k(-1)=7 is your answer.
Hope it helps!
