Graph the function f(x) = 4 (1/8)x and its reflection about the y-axis on the same axes, and give the y-intercept.

Solutions

Expert Solution

Consider the graph of the function;

f(x) = 4(1/8)x

 

Consider the graph is reflected about the y-axis, then;

f(-x) = 4(1/8)-x

 

The parent graph and the graph reflection on the y-axis are shown below;

 

To find the y-intercept set x = 0, as follows:

y = 4(1/8)0

   = 4

 

Therefore, y-intercept is (0, 4).


Therefore, y-intercept is (0, 4).
