Question

Help please
The graphs of four exponential functions are shown below:

graph of 4 exponential curves Curve P joins the ordered pairs negative 3.2, 20 and 0, 2 and 4, 0. Curve Q joins ordered pairs negative 2, 20 and 0, 5 and 6, 0. Curve R joins the ordered pairs negative 2, 0 and 0, 0.5 and 2.2, 20. Curve S joins the ordered pairs negative 2, 0 and 0, 0.5 and 3, 20

Which pair of graphs should be plotted to show the solution to 1 over 2 (3)x = 2 (1 over 2)x?

Graphs P and Q

Graphs Q and R

Graphs R and S

Graphs P and S

Answer 1

\[\frac{ 1 }{ 2 }(3)^x=2(\frac{ 1 }{ 2 })^x\]
