You are given an equation of the form
y = ax2 + bx + c.
y = 4x2 + 2x − 3
(a) Use a graphing utility to graph the equation and to estimate the x-intercepts. (Use a zoom-in process to obtain the estimates; keep zooming in until the first three decimal places of the estimate remain the same as you progress to the next step. Enter your answers as a comma-separated list.)
x =_________________

(b) Determine the exact values of the intercepts by using the quadratic formula. Then use a calculator to evaluate the expressions that you obtain. Round off the results to four decimal places. (Check to see that your results are consistent with the estimates in part (a). Enter your answers as a comma-separated list.)
x =_________________________
