Math Problem Statement
A function is described by the equation f(x) = -3x^2 + 5x - 2, in which f(x) is dependent on x. If a value for the independent variable is chosen from the set {-3, -2, -1, 0, 1}, which of the following would be a corresponding dependent value? Options: -14, 0, -2, 1, -1.
Solution
The problem provides the equation for a function:
We are tasked with finding the corresponding dependent value for values of chosen from the set { -3, -2, -1, 0, 1 }.
