Answer:
f(x) = -1 (x-9)^2
Step-by-step explanation:
To translate left or right, you must modify the x directly. As in (x-9). If you wanted to move it up or down you would do X^2 ± n, not directly modifying the x.
as well as, you are essentially making a new "zero" through this translation to (-9,0). i'm not sure if you're at that yet though.
as for the translation over the x axis.
when y is negative(or opposite), you have translated over the x-axis.
when x is negative(or opposite), you have translated over the y-axis.
Since you are doing the exponents, then the parenthesis, and then multiplying -1 last (by pemdas) you are ensuring that f(x), the output, or y, is always opposite or negative.

Step-by-step explanation:
Answer:
And then we have the following parameters for the random variable Y
And the best option is:e. mean = $4.35, variance = $ .30.
Step-by-step explanation:
For this case we know the following info " The toll on the bridge is $3.00 per car plus $ .50 per person in the car"
So then we can create the following linear function:
Where Y represent the total amount of money that is collected from a car. And X represent the number of people in the car.
We have the parameters for the random variable X given by:
So then we can find the expected value for the random variable Y like this:
And if we replace the expected value for X we got this:
Now we can find the variance for the random variable Y like this:
We know that for a number we don't have variance since is a constant and the covariance between a number and a random variable is 0 so then we have just this for the variance of Y:
And then we have the following parameters for the random variable Y
And the best option is:e. mean = $4.35, variance = $ .30.

Slope :
--------------------------
Slope = 5/8
--------------------------
Equation:
--------------------------
y = 5/8 x + b
--------------------------
Find y-intercept :
--------------------------
At (8, 2),
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3
--------------------------
Equation :
--------------------------
y = 5/8x - 3
-----------------------------------------------------------------
Answer: y = 5/8 x - 3
