Question

Evaluate the function y=3(1/2)^x for X=-3 A. -18 B. 24 C.9/8 D.-1/6

Answer 1

Answer:

B

Step-by-step explanation:

To evaluate the function, substitute x = -3. Since it is a negative exponent, it will create the reciprocal of the base.

$y = 3 (\frac{1}{2})^x\\\\y = 3 (\frac{1}{2})^{-3}\\\\y = 3 (\frac{2}{1})^3\\y = 3 (2^3)\\y = 3(8)\\y=24$
