Answer 2

Finding the Values of x for 2-4x to be Positive

To find the values of x for which the expression 2-4x takes on positive values, we can use the inequality 2-4x > 0 and solve for x.

Step 1: Set up the inequality 2-4x > 0.

Step 2: Solve for x.

The inequality 2-4x > 0 can be solved as follows:

2-4x > 0 -4x > -2 x < 1/2

Therefore, the expression 2-4x takes on positive values when x < 1/2.
