a
One of the graphs is of $y=4^x$y=4x and the other graph is of $y=6^x$y=6x.
Which is the graph of $y=6^x$y=6x?

Fill in the blanks to complete the statement:
For $x<\editable{}$x<, the graph of $y=\left(\editable{}\right)^x$y=()x is below the graph of $y=\left(\editable{}\right)^x$y=()x. This is because negative values of $x$x result in fractional function values, and for any negative value of $x$x, $\left(\editable{}\right)^x$()x will result in a smaller value than $\left(\editable{}\right)^x$()x.
