Where is this function positive?

To determine where a function is positive, we need to analyze the function’s behavior. If you’re considering a function like a quadratic or linear function, you would typically look at the roots and the leading coefficient.

For example, if the function is `f(x) = x + 5`, it is positive where `x > -5`. If it’s not specified, we can consider the context.

Based on the provided options:

– a) x < -5: This interval wouldn’t make the function positive if it crosses zero at `x = -5`.

– b) Not Applicable: This option does not specify conditions.

– c) x > -5: This means all values after -5 are positive.

– d) All Real Numbers: This depends on the function.

Without the specific function, the best answer is often c) x > -5, assuming that the function is linear or increasing past that point. If you can provide more details about the function, I could give a more precise answer!
