403) Subsitute \(x = 4x\) and simplify.

404) We need to transform x, which we can do by substituting \(x = x - 1\). This way, it becomes \(f((x-1) + 1) = f(x)\)

 

So, it would now become \((x-1)^2 + 3(x-1) + 5\)

405) First, we need to find x, so we have the equation: \(4x + 3 = -9\). Solve for x, and substitute this value into the function.

406) We know that \(x^2 - 6x \) equals either 9 or -9. Solve for x in both cases, and plug them back in to make sure they work.
