Chapter 3: Q. 12 (page 155)

Match each graph to one the following functions.
$f (x) = - x^{2} - 1$

Short Answer

Expert verified

The required graph is in option E.

Step by step solution

Step 1. Given information.

The given function is:

$f (x) = - x^{2} - 1$

Step 2. Identify the graph of the function.

The vertex of the function $f (x) = a (x - h)^{2} + k$ is $(h, k)$ . The graph opens up if $a > 0$ and it opens down if $a < 0$ .

In the given function $a = - 1, h = 0, k = - 1$ . So, the graph must be a downward parabola with vertex at $(0, - 1)$ .

Step 3. Conclusion.

The required graph is in option E.
