Answer:

The function is f(x) = 2x + 3 for x ≥ - 2 and f(x) = - 2x - 5 for, x < - 2.

The vertex of the function is (-2,-1)

Domain of the function is (-∞, +∞)

Range of the function is [-1, +∞).

Step-by-step explanation:

The function has a graph in two parts.

The right side part passes through the points (-2,-1) and (0,3).

So, the equation of this part will be  

\frac{y - 3}{3 - (- 1)} = \frac{x - 0}{0 - (- 2)}

⇒ y - 3 = 2x

⇒ y = 2x + 3

Again, the left side part of the graph passes through the points (-2,-1) and (-4,3).

Therefore, the equation of this part will be  

\frac{y - 3}{3 - (- 1)} = \frac{x - (- 4)}{- 4 - (- 2)}

⇒ y - 3 = - 2(x + 4)

⇒ y - 3 = - 2x - 8

⇒ y = - 2x - 5

Therefore, the function is f(x) = 2x + 3 for x ≥ - 2 and f(x) = - 2x - 5 for, x < - 2. (Answer)

The vertex of the function is (-2,-1) (Answer)

Domain of the function is (-∞, +∞) (Answer)

Range of the function is [-1, +∞). (Answer)

How can completing the square aid in solving quadratic functions?
Elden [556K]
Completing the squares tells us exactly what square root we will need to calculate our answer.

Using the formula below you can find these answers:
A(x-h)^2 + K = 0&#10;(x-5)^ 2 = - K/A&#10;

Does this make sense?
