i must sketch graph of these 2 functions

y=4log4x+1

y=e^3x

I am unsure how to find x and y intercepts for this problems could anyone please show me formula how to get coordinates to make this graph:rolleyes:

To find the interecept with x-axis, you must to solve the equation .

The graph does not intercept y-axis.

The graph does not intercept the x-axis.

To find the intercept with y-axis, you have to calculate :

Then give to some other values in the domain to find some other values for or .

Here are the sketches.
