Would 2 * -3^x be the graph of -2 * 3^x shifted up 4?

the 3 refers to the graph also passing through the point (1, 3).

So increasing when its 3^x and decreasing if its 3^-x

Im sure that guy knows a lot more about math than me but this seems wrong
The 2 being the intercept would be if there was a +2 wouldn’t it?
I mean if x=0
Then 3x=0
And 2*3x=0
So y would be 0
Or am I missing something?

f(x)=2•3^x
x=0, then y= 2•3=6!

I think he made a mistake there. The point shouldn’t be 2, but 6!

I'm not sure if I should spend my free time reviewing college crack open my old math texts?
