Answer:
Domain: [-1, inf) Range: [2, inf)
Step-by-step explanation:
Facts aboout a square root: Can never = be negative.
Thus x + 1 = 0, x = - 1
Domain: [-1, inf)
When (x+1)^1/2 = 0, m(x) = 2
Range: [2, inf)
5.5 + 2.1x + 3.8x - 4.1
5.5-4.1 +x(2.1+3.8)
1.4 +x(5.9)
5.9x+1.4
these are equivalent if there is a plus sign between 1.4 5.9x
