Question

Determine whether y = (0.5)^x-4 represents an exponential function. Explain why

Answer 1

Yes the given function is an exponential function

Explanation:

The general form of an exponential equation will have x as the exponent and we can write it as

`y = ab^x + c`

where a, b and c are constants

b is known as the growth factor

Since the given equation
`y = (0.5)^x-4` fits this pattern with a = 1, b = 0.5 and c = -4 this function is indeed an exponential function
