Unformatted text preview: 2. For each of the following quadratics (a) determine whether the quadratic crosses the x-axis, (b) the point where its slope is zero and (c) sketch its graph. (i) y=-2+x+x 2 (ii) y=-3+4x-x 2 (iii) y=1+x 2 : 3. Consider the following functions: y = 1 + x y = 9 & 5 x + x 2 : Solve mathematically for the points at which these two functions intersect. Show the second equation (the quadratic function) does not intersect the x-axis. Plot these two functions on the same graph. 1...
