I believe it’s B because it is not a function if there are 2 x values that are the same.

You roll a six-sided number cube and flip a coin. What is the probability of rolling a number less than 2 and flipping heads? Wr

lesya [120]

Answer:

1/12

Step-by-step explanation:

Number less than 2 is 1.

Probability of 1 out of 6 is:

P(1) = 1/6

Probability of heads is:

P(h) = 1/2

The probability of both is:

P = 1/6*1/2 = 1/12

Find the vertex and axis of symmetry for f(x)=2x^2-1

vfiekz [6]

<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

Solution:

Given is:

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

We have to find the vertex and axis of symmetry

The general equation is given as:

$f(x) = ax^2 + bx + c$

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

$x = \frac{-b}{2a}$

$x = \frac{0}{2(2)}\\\\x = 0$

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

$f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1$

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)
