Transcript text: Graph the function $f(x)=2\left(\frac{1}{2}\right)^{x-5}-5$ on the axes below. You must plot the asymptote and any two points with integer coordinates.
Solution
Solution Steps
Step 1: Find the horizontal asymptote
The horizontal asymptote is given by the vertical shift, which is $y = -5$.
Step 2: Find two points with integer coordinates
We are looking for two points with integer coordinates.
Let $x = 5$. Then $f(5) = 2(\frac{1}{2})^{5-5} - 5 = 2(\frac{1}{2})^0 - 5 = 2(1) - 5 = 2 - 5 = -3$.
Thus, the point is $(5, -3)$.
Let $x = 6$. Then $f(6) = 2(\frac{1}{2})^{6-5} - 5 = 2(\frac{1}{2})^1 - 5 = 2(\frac{1}{2}) - 5 = 1 - 5 = -4$.
Thus, the point is $(6, -4)$.
Final Answer:
The horizontal asymptote is $y = -5$. Two points on the graph are $(5, -3)$ and $(6, -4)$.
