Write the exponential function f(x)=-3*4^(1-x) in the form f(x)=ab^x

f(x)=-3*4^(1-x)

= -3 * 4^1 * 4^(-x)

= -12 4^(-x)

= -12 (1/4)^x

Step-by-step explanation:

Given function,

Using the product rule of exponent i.e.

Using power of power rule of exponent i.e.

Since,

Which is the required form of

Where,

a = -12, b = 1/4

so what is the question

step-by-step explanation:
