Check Enter y 2x and y 7 in a graphing calculator. 2x 7 Write original equation. The graphs intersect at about.
Log 2 2x log 2 7 Take log 2 of each side. 2x x 3 Property of Equality for Exponential Equations x 1 Solve for x. Note that the bases are not the same.
The exponential graph of a function represents the exponential function properties. If you ever plug a value in for a variable into an expression or equation youre using the Substitution Property of Equality. If b is a positive number other than 1 then b x b y if and only if x y.
Use the Power Property of Equality to solve exponential equations Distinguish between a linear and exponential function in the equation table and graph Describe the domain and range for an exponential function Graph an exponential growthdecay function. X log 2 7 log b b x x x 2807 Use a calculator. We can use this property to solve our exponential equation.
This property is quite useful when we are trying to solve equations involving exponential functions. The graph of function y2 x is shown below. The second is to make use of the Equality Property for Exponential Functions.
First the property of the exponential function graph when the base is greater than 1. In this non-linear system users are free to take whatever path through the material best serves their needs. Solving Exponential and Logarithmic Equations 76 Property of Equality for Exponential Functions bY iff x y 1.
