Answer
A) Sketch accordingly.
B) $x-intercept: (-2,0), (2,0), y-intercept: (0,-4).$
C) $symmetrical: y-axis$
Work Step by Step
For letter A, sketch accordingly.
For letter B, the graph drawn by you will provide the intercepts. If not, add "4" to the other side and take the square root of it to find both x-intercepts. For the y-intercept, plug in "0" for "x" and solve from there.
For letter C, the graph given is a parabola. A parabola that is symmetrical to the y-axis. Another reason behind this is that the equation is in "y=" format.
