How do I find the domain of the function.
P(x)=x©÷ - 2x +9
What is the domain of p
X ¡Á 0
X > 0
X ¡Á 9
To find the domain of a function, you need to consider the values of x for which the function is defined. In this case, we have the function P(x)=x©÷ - 2x + 9.
First, let's look for any restrictions on x in order to keep the function defined. In general, expressions like division or square roots cannot have denominators or arguments equal to zero, respectively.
For this specific function, there are no denominators or square roots involved, so there are no restrictions on x from these types of expressions.
Therefore, we can say that the domain of this function is all real numbers. In interval notation, we can represent the domain as (-∞, +∞) or simply as "all real numbers."
To summarize:
- The domain of P(x) = x©÷ - 2x + 9 is (-∞, +∞), or all real numbers.
