Plz ! which equation is represented by the graph? a.) f(x)= -2x|x+5|+4 b.) f(x)= -|x-5|+4 c.) f(x)= -|x+5|+4 d.) f(x)= -2|x-5|+4

The correct answer is D.) f(x)= -2|x-5|+4

In order to find this, we can first look for the vertex. In all absolute value functions, you can find the x value of the vertex by looking at the opposite of the number being add/subtracted inside of the absolute value symbol. In this case, the number is -5 is inside. The opposite would be x = 5.

The y value is always on the outside of the absolute value symbol and you don't have to change the sign. So, the y value should be 4.

Both B and D have these options, but we can differentiate the correct answer from the incorrect one by checking the slope of the line going to the right. Since it is -2, we choose the answer with the -2 in the front. This makes D the correct answer/

i think that you should ask google for the answer to that problem because if we don't know it google does

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

non hispanic white population

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
