compare a situation that you could use an exponential function to represent, to situations for which you would use another function .
Y=10-9^(x-3)
y=2x-4 y=2x+4 I'm confused by one being exponents but one isn't. How do I graph these? I try different x values like -1 and -2 but they don't appear similar...
The graph of y = f(x) = bx, where b > 1, is translated such that the equation of the new graph is expressed as y + 2 = f(x + 4). The domain of the new function is
Determine the points on the interval [0, 2π] where f(x)= esinx+cosx
The sales, S, of a product have declined in recent years. 1.8 million were sold in 2009 but only 1.2 million sold in 2012. Assume the sales are decreasing according to the exponential model S(t)=Soe^kt A...
The temperature, T ( Degree C), of a quenched steel plate at time t is given by T = f(t) = 10 + 85/1 + e^ (t−60)/10 where 0 ≤ t ≤ 100 measured in seconds. (a) We want to know...
Which of the following are exponential functions? A. f(x)=1x B. f(x)=0.8x+1 C. f(x)=(3.14)3x D. f(x)=(7/3)x E. f(x)=42x F. f(x)=−(2)x G. f(x)=(−2)x H. f(...
a rumour spreads in such a way that t hours after the rumour starts, the percent of people involved in passing it on is given by P(t)=100(e-t- e-4t). what is the highest percentage of people involved...

determine the derivative of the following: g(t)= e2t / 1+e2t
The temperature, T ( ?C), of a quenched steel plate at time t is given by T = f(t) = 10 + 85/1 + e (t−60)/10 where 0 ≤ t ≤ 100 measured in seconds. (a) We want to know when the...
In an effor to control vegetation overgrowth, 82 rabbits are released in an isolated area Free of predators. After 2 years, it is estimated that the rabbit population has increased to 328. Assuming...
The value of a machine, V, at the end of t years is given by V=C(1-R)t , where C is the original cost and r is the rate of depreciation. Find the value of a machine at the end of 4 years if the...
The revenue function is given by R(x) =x*p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=50(5)-x/5 find the revenue if 10 units are sold. Round to two decimal...
