WebJan 9, 2016 · y=4(1/2)^x An exponential function is in the general form y=a(b)^x We know the points (-1,8) and (1,2), so the following are true: 8=a(b^-1)=a/b 2=a(b^1)=ab Multiply both sides of the first equation by b to find that 8b=a Plug this into the second equation and solve for b: 2=(8b)b 2=8b^2 b^2=1/4 b=+-1/2 Two equations seem to be possible here. …

WebApr 9, 2024 · It is the difference between outputs of consecutive values of x. In other words, f(x + 1) = f(x) + (b − 1) ⋅ f(x). If negative, there is exponential decay; if positive, there is exponential growth. In more general terms, we have an exponential function, in which a constant base is raised to a variable exponent. hub abinteractive
