The value of [tex]f(15.4)[/tex] is B. 46.2.
Step-by-step explanation:
Step 1:
f(x) is dependent on the value of x.
So x is independent while f(x) is dependent on x i.e. the value of f(x) depends on the value of x.
Step 2:
[tex]f(x)= 3x.[/tex]
So if we have the value of x we can calculate the value of f(x). Here the value of x is given as 15.4 so f(x) when x equals 15.4 can be calculated.
[tex]f(x)= 3x, f(15.4) = 3(15.4),[/tex]
[tex]3(15.4) = 46.2.[/tex]
So the value of f(15.4) is 46.2 which is option B.
