Practice #1 - Graphing Parent Functions and their Features

Front

What is the parent function for a linear graph?

Back

f(x) = x

Front

Which parent function has a domain of all real numbers?

Back

Linear function, quadratic function, cubic function, and absolute value function all have a domain of all real numbers.

Front

What is the parent function for an absolute value graph?

Back

f(x) = |x|

Front

State the domain of the quadratic function in interval notation.

Back

(-∞, ∞)

Front

What is the general form of a quadratic function?

Back

f(x) = ax² + bx + c, where a, b, and c are constants.

Front

What is the parent function for a cubic graph?

Back

f(x) = x³

Front

What is the range of the absolute value function?

Back

[0, ∞) because the output is always non-negative.

Front

What is the parent function for a square root graph?

Back

f(x) = √x, defined for x ≥ 0.

Front

What is the domain of the square root function in interval notation?

Back

[0, ∞) because the function is only defined for non-negative values.

Front

What is the parent function for a rational function?

Back

f(x) = 1/x, which is undefined at x = 0.
