Use the function to find f(4)
f(x)=1/3•4^x

f(4) = 256/3

Step-by-step 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

The value of f(4) = 85.33

Step-by-step 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

i think the answer is b

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
