Β In an infantile paralysis epidemic 700 people contracted the disease. 400 received no serum treatment and of them 80 became paralyzed. Rest of the people received the serum treatment and among those 70 became paralyzed. can you tell the proportion of people receive and do not receive the serum treatment differ?

Reflect on the concept of function. What concepts (only the names) did you need to accommodate the concept of function in your mind? What is the simplest function you can imagine? In your day to day, is there any occurring fact that can be interpreted as a function? Is it possible to view a function? What strategy are you using to get the graph of a function?
1. Find the domain of the function using interval notation.
f(x)= \frac{ \sqrt{x-6} }{ \sqrt{x-4}
2. Sketch a graph of a piecewise function. Write the domain in interval notation.
[Suggestion: for example, go to www.desmos.com/calculator and write
y=x^2 for {-1 β€ x β€ 1}
and
y = 3x - 2 {1 β€ x β€ 3}
Then choose your own functions and have fun.]

The cost in dollars of making x items is given by the function C(x) = 10x + 500.
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
b. What is the cost of making 25 items?
c. Suppose the maximum cost allowed is $1500. What are the domain and range of the cost function, C(x)?
How do I find the values of more than one data in a set given the values of harmonic geometric and arithmetic mean i.e
In a study a set of observations were as follows:x,16,20b,4,25,c.Given that the geometric mean is 8.433 the arithmetic mean 11.25 and the harmonic mean 6.026 compute the values x y z
In each of the following functions determine it's
A.domain
B.range
C.x-intercept
D.zeroes
E.vertical asymptote
1y=log5(x-1)+3
2.y=log(3x-2)
Find the values of a and b that make f continuous everywhere,
f(x)={((x^(2)+6x+5)/(x^(2)-3x-4),x<-1),(ax^(2)-bx+3,-1<=x<3),(2x-a+b,x>=3):}
A haunted house charges $15 for entry and last weekend had 500 visitors. They would like to maximize their
profit, but research shows that if they increase the price by a dollar, they would receive 25 fewer visitors.
a. Write a quadratic model P(x), where P is the profit earned from changing the price by x dollars.
b. Will the haunted house be able to earn $8000 in a weekend? Why or why not?
c. How much would they make if they charged $25?
d. What is the maximum that the haunted house could make?
