Answer:
we CANNOT DIVIDE 3 with 6.
Step-by-step explanation:
Here,as given in the question:
Starting value = 6
Constant ratio = 1/3
Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.
⇒ f(x) = (Starting value) x (ratio)... x times
Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.
Hence, 
and 
Zeros are the x values which make the function equal to zero. Set it up as you would for a binomial with a constant multiplier "k" to account for the y-intercept (0, -5) given.
f(x) = k(x-2)(x-3)(x-5)
Use the y-intercept (0,-5) to solve for k.
-5 = k(0-2)(0-3)(0-5)
-5 = -30k
-5/-30 = k
1/6 = k
The cubic polynomial function is then ..
f(x) = (1/6)(x-2)(x-3)(x-5)
Linear factors are the linear (line) expressions you can factor out of the polynomial. They are (x-2), (x-3) and (x-5).
Considering the box and whisker plot, it is found that the number of dogs that weigh more than 35 pounds is given by:
C. 75
<h3>What does the box plot shows?</h3>
It shots the first quartile, the median and the third quartile. In this problem:
- The first quartile is of 35.
- The third quartile is of 70.
The first quartile of 35 means that 25% of the measures are less than 35, and 75% are more, hence, out of 100:
0.75 x 100 = 75
Which means that option C is correct.
