## The steps in writing f(x)=18x+3×2 in vertex form are shown, but a value is missing in the last step. Write the function in stand

Question

The steps in writing f(x)=18x+3×2 in vertex form are shown, but a value is missing in the last step.

Write the function in standard form.

Factor a out of the first two terms. f(x)=3(x2+6x)

Form a perfect square trinomial. (six-halves) squared

f(x)=3(x2+6x+9)−3(9)

Write the trinomial as a binomial squared. f(x)=3(x+___)2−27

Answer:Step-by-step explanation:we have

Write the function in standard form

Factor 3 out of the first two terms

Form a perfect square trinomial. (six-halves) squared

Write the trinomial as a binomial squared

therefore

The vertex is the point (-3,-27)
