2k - 18 is the answer. Whenever there's something (I.e. A number or variable) attached to a parenthesis, it means you need to multiply everything inside that parentheses to get the product

(k-9)²
=(k-9)(k-9)
=k(k)-9(k)-9(k)-9(-9)
=k²-9k-9k+81
=k²-18k+81. As a result, the product of (k – 9)2 using the perfect square trinomial rule shown on the left is k²-18k+81. Hope it help!

If the result is reflected over x-axis and vertically stretched by a factor of 5, the result will be g(x) = -5(x - 1)²

<h3>Transformation of functions</h3>

Transformation is a way of changing the position of an object o the xy plane. Given the parent function expressed as

f(x) = x^2

If the function is shifted to the left by unit, then we will have h(x) = (x - 1)²

If the result is reflected over x-axis and vertically stretched by a factor of 5, the result will be g(x) = -5(x - 1)²
