1/15뒤로Skip to main content뒤로What is the domain of the constant function f(x) = c?
The domain is all real numbers, meaning any x value can be input. What is the range of the constant function f(x) = c?
The range is just the constant c, so only one possible output. What is the domain of the identity function f(x) = x?
The domain is all real numbers, so any x value can be used. What is the range of the identity function f(x) = x?
The range is all real numbers, since any output is possible. What shape does the graph of the square function f(x) = x^2 form?
It forms a parabola, which is a bowl-like shape. What is the domain of the square function f(x) = x^2?
The domain is all real numbers, so any x value can be input. What is the range of the square function f(x) = x^2?
The range is from 0 to positive infinity, including 0. What is the domain of the cube function f(x) = x^3?
The domain is all real numbers, so any x value can be input. What is the range of the cube function f(x) = x^3?
The range is all real numbers, so any y value is possible. What is the domain of the square root function f(x) = √x?
The domain is from 0 to positive infinity, including 0. What is the range of the square root function f(x) = √x?
The range is from 0 to positive infinity, including 0. Why can't negative x values be used in the square root function f(x) = √x?
Negative x values are not included because the square root of a negative number is not defined in real numbers. What is the domain of the cube root function f(x) = ∛x?
The domain is all real numbers, so any x value can be input. What is the range of the cube root function f(x) = ∛x?
The range is all real numbers, so any y value is possible. Which common function has both domain and range restricted to non-negative values?
The square root function f(x) = √x has both domain and range restricted to non-negative values.
