Final answer:
The domain of the function c=8.49x is all real numbers, meaning there is no restriction on the x-values that can be put into the function. It extends from negative infinity to positive infinity.
Step-by-step explanation:
The question is asking for the domain of the function c=8.49x. In mathematics, the domain refers to the set of all possible input values (x-values) for which the function is defined. In this case, since there are no restrictions such as square roots of negative numbers or divisions by zero, the domain of the function is all real numbers. This is because for every real number that you substitute for x, the equation will produce a real number for c.
Mathematically, the domain of the function c=8.49x is expressed as:
Domain: x
In interval notation, this would be (-∞, ∞), which means the domain extends from negative infinity to positive infinity.
