Converting from logarithmic form to exponential form. khanacademy. 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. 99 USD per week until cancelled: Monthly Subscription $6. The symbol ab, where. MalMath is a math problem solver with step by step description and graph view. symbolab. The calculator will find the linear approximation to the explicit, polar, parametric and implicit curve at the given point, with steps shown. To do this we simply need to remember the following exponent property. Exponential regression is probably one of the simplest nonlinear regression models.
