Constant6. If the leading coefficient of a quadratic function is positive, then the graph of the function extends from: A. Quadrant III to Quadrant IV B. Quadrant II to Quadrant I C. Quadrant II to Quadrant IV D. Quadrant III to Quadrant I 7. Sophia described the characteristics of / (x) = -2x3 + 7x3 - 9x, but there is an error. Identify the error. A. This is a polynomail function of degree 3, so I know that the graph could have two turning points B. The y-intercept is at -9 because the last term is -9x. C. The leading coefficient of this cubic function is negative, so I know that the graph extends from Oll to QIV D.
