Solve the quadratic equation numerically (using tables of x and y values) x squared 2 x 1 = 0 a x = 1 c x = 3 b x = 1 or x = 3 d x = 2 or x = 1 chooseA Few Notes about Example 2 This equation, y = 1/2 x 1 has a fraction as the coefficient of x This becomes a little trickier in choosing x coordinates because we could end up with a fraction for the y coordinate This then becomes a little more difficult to graph So, the trick is to look at the denominator of the coefficientTable of Basic Integrals Basic Forms (1) Z xndx= 1 n 1 xn1;
