Answer 2

Finding the Intervals where f(x) = 20x + 4 is Positive

To determine the intervals where the function f(x) = 20x + 4 is positive, we need to find the values of x for which f(x) is greater than zero.

The function f(x) = 20x + 4 is a linear function with a positive slope of 20. This means that as x increases, the value of f(x) also increases.

To find the intervals where f(x) is positive, we need to solve the inequality 20x + 4 > 0.

Subtracting 4 from both sides of the inequality, we get: 20x > -4

Dividing both sides of the inequality by 20, we get: x > -4/20

Simplifying the expression, we have: x > -1/5

Therefore, the function f(x) = 20x + 4 is positive for all values of x greater than -1/5.

In interval notation, we can express this as: x ∈ (-1/5, ∞)

This means that the function f(x) = 20x + 4 is positive for all values of x greater than -1/5.
