Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (- infinity, infinity)
Range: (- infinity, -2)
5 goes with total numbers in the ride
k goes with number of kilometers he has already biked
5-k goes with numbers of kilometers left
and then proces of elimination leaves you with 4 and the last one
X+5 ≤ -17
Or if it’s y instead of x put that.
Hope this helps though
If your looking for the value of "x" it is 4.
Hope this helped!
