Question

Which of the following represents the range if the function g(x) below? G(x) = 5(x - 2) ^ 2 - 7

Answer 1

Answer:

[-7,∞)

Step-by-step explanation:

This function is a parabola that has a positive coefficient, so the parabola will open upwards (or make a smile if you want to call it that). The vertex is located at (2,-7) because of the vertex equation, so you know that the y values are greater than or equal to -7.
