A) give a verbal description of the subset of real numbers represented by the inequality or the interval, b) sketch the subset on the rest of real number line, and c) state whether the interval is bounded or unbounded

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
