Question

F(x)=5•0.3^x is it exponential

Answer 1

Answer:

Yes, this is an exponential function.

Step-by-step explanation:

this is the general form of an exponential function:

$f(x) = ab^{x}$

As long as:

• b $\neq$ 1,
• a > 0,
• b > 0,

then, if you see x in the exponent of an equation, it's generally going to be an exponential function.

Learn extra:

Even more specifically, this function is considered to be "exponential decay" because "b" is greater than 0 and less than 1.

If "b" had been greater than 0, it would be called "exponential growth."
