Question

Find the domain and range, x and y intercepts of the rational function

Answer 1

\[f(x)= \frac{ 2 }{ x ^{2}-2x-3}\]

Answer 2

domain set of x values
range set of y values
x-intercept when y = 0
y-intercept when x = 0
restrictions values of x that will make the denominator zero you do not want to divide by zero

Answer 3

factor the quadratic
