Answer:
x > -1
Step-by-step explanation:
p = (f o g)(x) = log ((x+4)-3)
p = log (x+1)
so that p has a value,
the value of x + 1 mus be greater than 0
x + 1 > 0
x > -1
so the domain is x > -1
Domain = {x | x > -1, x must real number}
Answer:
Step-by-step explanation:
7. 1/4 of 84 is 21, then 1/3 of that is 7
The factored form of 9x^2 + 12x + 4 is:
(3x+2)(3x+2) or (3x+2)^2
