Unformatted text preview: 2. For each of the following quadratics (a) determine whether the quadratic crosses the xaxis, (b) the point where its slope is zero and (c) sketch its graph. (i) y=2+x+x 2 (ii) y=3+4xx 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 xaxis. Plot these two functions on the same graph. 1...
