Question

Calculator Bookwork code: K81 X not allowed The function g is shown below. g(x) = x² + 9x Write an expression for g(x + 4) in the form a2 + ax + b, where a and b are numbers.​

Answer 1

Answer: g(x + 4) = (x + 4)² + 9(x + 4)

= x² + 8x + 16 + 9x + 36

= x² + 17x + 52

So, an expression for g(x + 4) in the form a2 + ax + b, where a and b are numbers, is 1x^2 + 17x + 52
