Answer:

y = .5x^2 -2x -5

Step-by-step explanation:

Well we can start by seeing if the parabola is the same width by comparing it to its parent function ( y = x^2 )

In y = x^2 the 2nd lowest point is just up 1 and right 1 away from the vertex.

This is not true for our parabola.

So we can widen it by to the desidered width by making the x^2 into a .5x^2.

So far we’ve got y = .5x^2

Now the parabola y intercept is at -5.

So we can add a -5 into the equation making it.

y = .5x^2 - 5

Now for the x value.

So we can find the x value by seeing how far away the parabola is from from the y axis.

So the x value is -2x.

So the full equation is y = .5x^2 -2x -5

Look at the image below to compare.

Art [367]

The value of the game will be $ 0.08. Then the correct option is B.

<h3>What is probability?</h3>

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

A game is played by rolling a fair six-sided die once.

If the die lands on a 1 the player win $8 otherwise the player loses $1.50.

Then the value of the game will be

The probability of success will be

p = 1/6

The probability of failure will be

p = 5/6

Then the value of the game will be

Value of game = 8p - 1.5q

Value of game = 8 x 1/6 - 1.5 x 5/6

Value of game = 1.3333 - 1.25

Value of game = 0.08333

Value of game ≅ $ 0.08

More about the probability link is given below.
