graph the exponential function.\n$f(x)=2^{x}$\nplot five points on the graph of the function. then click on the graph - a - function button.
Answer
Explanation:
Step1: Substitute (x = - 2)
When (x=-2), (y = f(-2)=2^{-2}=\frac{1}{2^{2}}=\frac{1}{4})
Step2: Substitute (x=-1)
When (x = - 1), (y=f(-1)=2^{-1}=\frac{1}{2^{1}}=\frac{1}{2})
Step3: Substitute (x = 0)
When (x = 0), (y=f(0)=2^{0}=1) (since (a^{0}=1,a\neq0))
Step4: Substitute (x = 1)
When (x = 1), (y=f(1)=2^{1}=2)
Step5: Substitute (x = 2)
When (x = 2), (y=f(2)=2^{2}=4)
Answer:
The five points are ((-2,\frac{1}{4}),(-1,\frac{1}{2}),(0,1),(1,2),(2,4))
