Answer:

Domain → (-∞, ∞)

Range → (-∞, 5)

Explanation:

Domain of a function is a set of x-values (input values) for which the function is defined.

Function A is a quadratic function (in the form of a parabola) opening downwards.

This function is defined for every input value from negative infinity to positive infinity.

Therefore, domain of the given function A is (-∞, ∞).

Similarly, y-values (output values) vary from negative infinity to 5.

Therefore, range of the given quadratic function will be (-∞, 5).
