Answer and Explanation:
The relative minimum y-value of a curve is the lowest point on the curve where the slope of the tangent line is 0—in other words, where the curve changes direction, opening upwards. We can see that the minimum of this curve (
) is approximately (3, -6).
__
The leftmost x-value given by the curve (that we can see on the graph) is approximately -1.
__
The roots, or zeros, of a function are the x-values where the function crosses the x-axis—in other words, where the function's output is 0.
We can see that these x-values are x = 0, x = 1, and x = 4.
