Lesson 1

Description: <p>Graph of two polynomial functions on x y plane. Horizontal axis, scale negative 10 to 10, by 2’s. Vertical axis, scale negative 20 to 35, by 5’s. Bue function is y = f(x) and is through (negative 4 comma 0), (0 comma 0) and (2 comma 0). The other function goes through (negative 8 comma 15), (negative 6 comma 10) and (negative 4 comma negative 5) and is y = g(x) and is green.</p>

Description: <p>Graph of two polynomial functions on x y plane. Green function is y = g(x) and is above the x - axis and has a local maximum at point (2 comma 2) and another through (negative 2 comma 2). Blue function is y = f(x) and is above and below the x - axis and has a local maximum through (0 comma 1). </p>

Description: <p>Graph of two quadratic functions on x y plane. Horizontal axis, scale negative 4 to 4, by 1’s. Vertical axis, scale negative 4 to 4, by 1’s. Upright blue function is y = f(x) and is y = x^2, and the other function is upside down, vertex at (0 comma 3) and is y = g(x).</p>

Description: <p>Graph of a cubic polynomial function, x y plane, starts in quadrant 3, goes (negative 1, negative 1), flattens out as it goes through the origin and then through (1 comma 1) and rises rapidly. There is a point at (negative 1 comma 1).</p>

Description: <p>A graph of a function on a coordinate plane. X axis from negative 7 to 6, by 1’s. Y axis from negative 4 to 7, by 1’s. From left to right, the function begins in the second quadrant, moves downward and to the right, crossing through negative 6 comma 6, negative 2 comma 2 and touching the x axis at approximately 0. It continues and to the left crossing through 2 comma 2 and 6 comma 6 then continues to move upward and to the right, ending in the first quadrant. Points negative 4 comma 2 and 4 comma 2 are shown.</p>

Description: <p>Graph of a function. Horizontal axis, scale is negative 4 to 6, by 1’s. Vertical axis, scale is negative 10 to 8, by 2’s. 17 data points graphed. From left to right, function starts around negative 2 point 75 comma 10 crosses the x axis at 2 has a local maximum around negative 1 comma 4, moves downward and to the right to 1 comma 0, then moves upward and to the right through 2 comma 4, then continuing to move upward and to the right.</p>

Description: <p>Graph of two inverse functions on x y plane. Horizontal axis, scale negative 10 to 10 by 2’s. Vertical axis, scale negative 6 to 6 by 1’s. Blue function has a vertical asymptote at x = 0 and a horizontal asymptote at y = 0. Blue graph displays in Quadrant 1 and Quadrant 2 only. Green function is discrete and has a vertical asymptote at x = 2 and a horizontal asymptote at y = 1. Green graph displays in Quadrants 1, 2 and 4.</p>

Description: <p>Graph of two quadratic functions on x y plane. Horizontal axis, scale negative 6 to 6, by 1’s. Vertical axis, scale negative 6 to 6, by 1’s. Upright blue function is y = x^2, and the other function is green and discrete, is upside down and vertex at (2 comma 5).</p>
