f(x) =
In this exponential function , the base is
if base is less than 1 then it a decreasing function
We can verify it using a table
We plug in some x and values and find out f(x) to get point for the graph
x -----> f(x)
-1 -----> 2
0 ------> 1
1 -------> 0.5
The table is same as the points in first graph.
So first graph represents the graph of f(x) =
Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping
So, if you have a x/y values table, you simply have to change sign to all the values in the y column.
