Step-by-step explanation:
A relation is a function in which for each input there is only one output.
In a relation, y is a function of x.
Now we look at the mapping
For input 6, -1 is the output
for input -1, 2 is the output
for input 4, 3 is the output
for input 0, 3 is the output
For each input , there is an output. Input is not repeating. Input is occurring only once.
So this relation is a function.
Answer:
(4x+4)
Step-by-step explanation:
h(x)=5x+6
k(x)=9x-2
(k-h)(x)= (9x-2-5x+6)
9x-5x=4x -2+6=4
(k-h)(x)= (4x+4)
