PLEASE HELP ASAP!!!!!!
1.) let f (x) = x2 + 5x + 4. so... f(3x-5)= ?
2.) Use the graph that is pictured: find the domain and range of f
3.) use the other picture of the tables: which of the tables could represent a linear function? For each that could be linear, find a linear equation that models the data.
4.)A town’s population has been growing linearly. In 2008, the population was 120,000, and the popu- lation has been growing by 3,400 people each year. Write an equation, P(t), for the population t years after 2008.
5.) Use the previous promt to answer^-Predict the population in 2019. as well as ->Identify the year in which the population will reach 80,000
6.)find a linear functions that satisfies the following properties: f(−1) = 4, f(3) = −2 as well as ->Passing through (4,−1) and (1,3).
7.)When a ball is tossed into the air, the height h is feet of the ball t seconds from the time that the ball is released is given by the formula
h(x)=−16t2+80t+4.
Determine the maximum height of the ball and the time that the ball will obtain that heigh
8.)The profit P in dollars earned on the produc- tion and sale of USB drives with a sale price of x dollars per drive is given by the formula
P(x)=−1.2x2+288x−30, 10≤x≤180.
Find the price that maximizes the profit, and find the maximum profit.
