Question

Which best describes the domain and range of the function y = = 4x²?​

Answer 1

Domain: (-infinity, infinity)

Range: [0, infinity)

Explanation:

y = 4x^2 is a quadratic function whose parabolic graph goes through (0, 0) and opens upward. (0, 0) is both the vertex and the minimum of this function and graph. Here x can take on any value, but y is limited to [0, infinity).
