Question

Find f(5) for f (x)=1/4 (2)^x

Answer 1

Your function is f(x)=1/4(2)^x

f(5)=1/4 (2)^5           Apply the exponent to the value inside the parentheses

f(5)=1/4 x 32            Multiply 1/4 and 32

f(5)= 8

Your answer is A. 8

Answer 2

The correct option is A. 8

Given f (x)=1/4 (2)^x.

$f(x)$ $=\frac{1}{4} 2^{x}$

We have to calculate F(5), means put x = 5.

So, $f(5)=\frac{1}{4} 2^{5}$

$f(5)=\frac{1}{4} \times 32$

$f(5)=8$

Hence $f(5)=8$ .
