d^2 + 6d + 9 = (d+3)^2

g((d+3)^2) = 3(d+3)^2 + Y(d+3)^2

So... what's the question?

:D

\(g(x) = 3x + \sqrt{x}\)

\(g(d^2 +6d+9) = g(d + 3)^2\)

Lets denote \((d + 3)^2 = y\)

\(g(y) = 3y + \sqrt{y}\)

\(g(y) = 3(d + 3)^2 + \sqrt{(d+3)^2}\)

Hi nelvin898, Could you please provide with further information on the question, what is the question asking for , what are the answer choices and what is the OA.

Thank you.
