Question

is y=-3(4^x) an exponential function

Answer 1

What do you think?

Answer 2

What do you think? What makes a function an "exponential function"?

Answer 3

I think it is.

Answer 4

Right... :) because an exponential function has the variable in the exponent. Something of the form:

\(\Large y=b^x\)

And the constant of -3 out in front, that is just a reflection and a vertical stretch. :)

Thanks, best responce.
