Question

Determine the output, f(x), if the input to the function box below is 8.

f(x)=3x-1

Answer 1

The output is 23

Explanation:

we know that

f(x) ----> is the output

x ----> is the input

we have that

f(x)=3x-1

For x=8 (input)

Find the value of f(x) (output)

f(8)=3(8)-1=23

The output is 23
