Question

Change the quadratic function into vertex form.

Answer 1

(-1, -6)

Explanation:

1. Identify the coefficients

a = 1/4 b = 1/2

2. Substitute the coefficients in the equation.

x = -b/2a

3. Solve the equation.

x = -1

4. Evaluate the function for x = -1 (to find y).

5. Calculate the function value.

6. y = -6
