Determine an equation of a exponential function of base 2 with the following characteristics. - Horizontal asymptote: y=4 - Range: y<4 - Y-Intercept (0,2)
a radioactive substance decays according to the equation A(t)=A0(0.1)0.073, where t is in years and A0+1 is the original amount of the substance. How long will it take until there is only...
A radioactive substance decays according to the equation A(t)= A0().1)0.073t, where t is in years and A0=1 is the original amount of the substance. How long will it take until there is only 10% of...
The pH scale is defined as pH= -log [H+], where [H+] is the concentration of hydronium ions, measured in mole per litre. If pH > 7, the solution is basic. If pH...

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
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...
