If f(x) = -x2 – 1, and
g(x) = x + 5, then
g(f(x)) = [ ? ]x2+[ ]x+[]

-x^2 +4

Step-by-step explanation:

f(x) = -x^2 – 1, and

g(x) = x + 5,

g(f(x)) = Plug f(x) in for x in g(x)

          =-x^2-1 +5

          =-x^2 +4

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: just subtact the units and then add the non negative : happy to
