Question

Use the function to find f(4)

f(x)=1/3•4^x

Answer 1

The value of f(4) = 85.33

Explanation:

It is given a function f(x),

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

To find the value of f(4)

To find the value of f(4) we have to substitute 4 instead of x

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

bstitute x = 4 we get,

f(4) = (1/3) * 4^4

= (1/3) * 256

= 85.33

Therefore the value of f(4) = 85.33

Answer 2

f(4) = 256/3

Explanation:

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

f(4) = 1/3 * 4 ^4

4^4=4*4*4*4 = 256

f(4) = 1/3 * 256

f(4) = 256/3
