Find an exponential equation from two points
WebAboutTranscript. We can use logarithms to solve *any* exponential equation of the form a⋅bᶜˣ=d. For example, this is how you can solve 3⋅10²ˣ=7: 1. Divide by 3: 10²ˣ=7/3. 2. Use the definition of logarithm: 2x=log (7/3) 3. Divide by 2: x=log (7/3)/2 Now you can use a calculator to find the solution of the equation as a rounded ... WebWe will construct two functions. The first function is exponential. We will start with an initial input of 0 with a corresponding output of 1, and increase each consecutive input by 1. We will double the corresponding consecutive outputs. The second function is linear.

To find the equation, you need to find the values of a and b. 1. To find b, take the ratio of f at the two known points, f (3)/f (2)): 270/90 = a*b 3 /a*b 2 = b 3 = b 2. So far we have f (x) = a*3 x . To find the value of a, plug in one of the known points. I'll use (2,90):

Plug in the first point into the formula y = abx to get your first equation. 2. Plug in the second point …
WebThis can be easily be determined by a change in the asymptote. If you see an asymptote at say y=3, then "act like" this is the y axis and see how far points are away from the this line. Thus y=2^x + 3 would have points (0,4) 1 away from asymptote, (1,5) two away from asymptote, etc. Thus, you would have to do (5- 3)/(4 - 3) to get 2/1=2 as the ...
