Question

Compare the domain and the range for the parent quadratic function to the domain and the range for the parent linear function

Answer 1

The parent quadratic function is:
y = x²
Domain : x ∈ R
Range: y ∈ [ 0, + ∞ )
The parent linear function:
y = x
Domain : x ∈ R
Range : y ∈ R
Answer: The domain of the parent quadratic function is the same as the parent linear function but the range is not the same.
