Question

what is the domain of this quadratic function?
options:
\\{x|x \geq -3\\}
\\{x|x \geq -2\\}
\\{x|-2 \leq x \leq 0\\}
all real numbers

Explanation:

The domain of a function is all possible x-values for which the function is defined. For quadratic functions, their graphs (parabolas) extend infinitely horizontally in both directions, so there are no restrictions on the x-values that can be input into the function.

Answer:

all real numbers
