Question

select the correct answer.
consider functions h and k
table with x values 0,1,2,3 and h(x) values 1,4,10,28
function k represented by a mapping diagram with x values 0,1,2,3,4 and k(x) values 4,3,2,1,0
what is the value of (h ∘ k)(1)?
a. 1
b. 4
c. 28
d. 0

Explanation:

Step1: Find k(1) from mapping

From the arrow diagram, $k(1)=3$

Step2: Compute h(k(1)) = h(3)

From the table, $h(3)=28$

Answer:

C. 28
