Question

Does the rule y = -3(4^x) represent an exponential function?

Yes
No

Answer 1

Any ideas?

Answer 2

I think yes

Answer 3

and why do you think yes?

Answer 4

More importantly, what IS an exponential function?

Answer 5

Like a pattern

Answer 6

Is f(x) = 4x^6 and exponential function?

Answer 7

An exponential function is a certain type of pattern. Should I explain it more clearly?

Answer 8

Yeah and no you don't have to explain (:

Answer 9

Well, f(x) = 4x^6 is not an exponential function

Answer 10

So this is not an exponential function

Answer 11

Okay, let me explain what exactly an exponential function is.

It's a function where the independent variable is an exponent.

For example f(x) = 4^x
However in the case of f(x) = 4x^6 the independent variable is a base. So it is isn't exponential function, but a power function. It is also a polynomial.
