Graph y=-1/2x^2-1. Identify the vertex of the graph. tell whether it is a minimum or maximum. (To clarify, 1/2 is a fraction *x^

ahrayia [7]

$y= -\frac{1}{2} x^{2}-1$ is a quadratic function, so its graph is a parabola.

Notice that the coefficient of x is 0, this always means that the axis of symmetry is the y-axis.

That is, the vertex of the parabola is in the y-axis, so the x-coordinate of the vertex is 0.

for x=0, y=-1. So the vertex is (0, -1)

The coefficient of $x^{2}$ is negative. This means that the parabola opens downwards, so the vertex is a maximum.

Answer: (0, -1) , maximum (none of the choices)

<h3>Further explanation</h3>

The probability of an event is defined as the possibility of an event occurring against sample space.

$\large { \boxed {P(A) = \frac{\text{Number of Favorable Outcomes to A}}{\text {Total Number of Outcomes}} } }$

<h2>Permutation ( Arrangement )</h2>

Permutation is the number of ways to arrange objects.

$\large {\boxed {^nP_r = \frac{n!}{(n - r)!} } }$

<h2>Combination ( Selection )</h2>

Combination is the number of ways to select objects.

$\large {\boxed {^nC_r = \frac{n!}{r! (n - r)!} } }$

<em>Let us tackle the problem!</em>

$\texttt{ }$

This problem is about Combination.

<em>Peter is selling Hazelnut (H), Chocolate (C), Tiramisu (T), Pistachio (P), and Strawberry (S). Total Combinations will be:</em>

$^5 C_3 = \frac{5!}{( 5 - 3 )! 3!}$

$^5 C_3 = \frac{5!}{ 2 ! 3 !}$

$^5 C_3 = 5 \times 4 \div 2$

$^5 C_3 = \boxed{10}$

<em>List of Possible Combinations:</em>
