Find (fog)(x) and the domain

(fog)(x) = 2sqrt(x) + 3

Domain: {x | x ∈ R, x>=0}

Step-by-step explanation:

(fog)(x) = f(g(x))

let f(a) = f(g(x))

f(a) = 2a+3 = 2(g(x)) + 3 = 2sqrt(x) + 3

To find domain, pick most restricting domain of the functions that make up the compound function.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

if you was gonna solve for a, a is a   < -12
