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

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
