Answer: 11
Step-by-step explanation:
plug in 4 any instance you see "x"
f(x) = 3x - 1
f(4) = 3(4) - 1 = 11
Functions are mappings who map inputs to at max one corresponding outputs. The value of function at x=4 is: [tex]f(4) = 11[/tex]
You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For given case, we have:
[tex]f(x) = 3x - 1[/tex]
Taking x = 4, we get:
[tex]f(4) = 3(4) - 1 = 3 \times 4 - 1 = 12 - 1\\f(4) = 11[/tex]
Thus, The value of function at x=4 is: f(4) = 11
