Question

Find the range given the domain:
y= 6 over x + 1
Domain: {-2, 3, 6}

Answer 1

When x = -2, y = 6/(x+1) = 6/(-2+1) = 6/(-1) = -6


So when x = -2, y = -6



When x = 3, y = 6/(x+1) = 6/(3+1) = 6/(4) = 3/2


So when x = 3, y = 3/2



When x = 6, y = 6/(x+1) = 6/(6+1) = 6/7


So when x = 6, y = 6/7


So the range is {-6, 3/2, 6/7}
