The function f(x) = (x − 4)(x − 2) is shown. On a coordinate plane, a parabola opens up. It goes through (2, 0), has a vertex at (3, negative 1), and goes through (4, 0). What is the range of the function? all real numbers less than or equal to 3 all real numbers less than or equal to −1 all real numbers greater than or equal to 3 all real numbers greater than or equal to −1
here's the graph, which one do you think, it should be easy range is the y axis
thats it there
yes, and as you an see, it goes up from -1, so which one do you think
ready for the next 1
