If a(x) = 3x + 1 and b(x)= VX-4, what is the domain of (bºa)(x)? 0 (-0,00)
0 (0.00)
O [1,00)
O [4,00)

 [4,∞)

Step-by-step explanation: This is a composite function so we must respect both domain of a(x) and b(x). a(x) domain is all real numbers because you can plug any x-value into a linear function. However b(x) domain is all real numbers greater than or equal to 4 because you can take the sqr root of a negative number  so anything under 4 won't work. We can take the sqr root of 0 so we must include 4. (4-4=0)   Now let respect both functions. We can't use any number under 4 so we must start at 4 so we used a closed bracket also we can use anything positive infinity number greater than 4 so we use a paretheses to showed unboundness so it is [4,∞).
