i need help solving each of these. Please help me understand how to do each problem as I actually want to know how to solve it and get the correct answer. please give steps if possible and thank you
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.
