1. Exponential Functions
Sign In
Make a table to find ordered pairs. Then, plot and connect the points with a smooth curve.
Graph:
Domain: All real numbers
Range: y<-3
To graph the given function, we will first make a table of values.
x | -(1/2)^(x+1)-3 | y=-(1/2)^(x+1)-3 |
---|---|---|
-3 | -(1/2)^(-3+1)-3 | -7 |
-2 | -(1/2)^(-2+1)-3 | -5 |
-1 | -(1/2)^(-1+1)-3 | -4 |
0 | -(1/2)^(0+1)-3 | -3.5 |
1 | -(1/2)^(1+1)-3 | -3.25 |
Let's now plot and connect the points ( -3, -7), ( -2, -5), ( -1, -4), ( 0, -3.5), and ( 1, -3.25) with a smooth curve.
We can see that the graph approaches the line y=- 3 but does not intersect it. Therefore, the range is all real numbers less than -3. The domain of the function is all real numbers. Domain:& All real numbers Range:& y<-3
