Due tonight! PLEASE HELP The graph of a quadratic function has a domain of (-∞, ∞) and range of [4, ∞). In two or more complete sentences, explain how the given range of the function can help you to determine whether the graph opens up or down.

Step-by-step explanation:

The range is:

It means the lowest point is 4 and all the other points are greater than 4

Point 4 is the y-coordinate of the vertex and the graph opens up.

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
