Question: Graph the function f ( x ) = 5 ( o . 5 ) x and its reflection about the line y=x on the same
Graph the function f(x)=5(o.5)x and its reflection about the line y=x on the same axis, and give the x-intercept of the reflection. Prove that ax=exlna . [Suggestion: type y=5(0.5^{-x}){- 7 < x < 2}{0 < y < 7} into the desmos graphing calculator, and then type its inverse function.]
