why is the graph of y = -2^x downwards?? how is that possible?

Question

i was studying exponential functions and im very confused...

Answer 1

Maybe this will help.

y = -2^x

= -1(2^x).

2^x is exponential growth with base of 2.

So it is a rapid positive or upwards growth For increasing positive values of x

,

BUT

multiplication by a factor of -1 reverses the direction of the growth.

Thus making y= -2^x have rapid downward growth for increasing positive values of x.
