Given f(x) = 3x - 5, find f(-2).

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.

47 - 90 = 43

43 - 180 = x

x = 137

14.29%
