The value of f(-2) = -11.
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:
f(x) = 3x - 5, if we have the x's value we can calculate the f(x)'s value. Here the value of x is given as -2 so f(x) when x equals -2 can be calculated.
[tex]f(x) = 3x-5. f(-2) = 3(-2)-5 = -6-5 = -11.[/tex]
