Problem

Consider the polynomial

f(x)=x^{2}-2x-3

. a. (i) Calculate

f(x)

for

x=-1,0,1,2,3

and list the ordered pairs

(x,f(x))

. b. (ii) Using your results, state the coordinates of the

x

-intercepts and the

y

-intercept of the graph. c. (iii) Does the graph exhibit symmetry about the

y

-axis? Give a brief reason.
