1.) Let the function; f(x)= (2x+4)/(3x+2)(9x+1).
a.) Determine x-intercept(s).
If there is more than one x-intercept write the list of x-intercepts separated by commas (i.e.: (1,2),(3,4)). If there is no x-intercept type in none.
b.) Compute domain. Write the comma separated list of all x values which are not in domain. If there are no such x, type none.
2.) Let the function: f(x)= (x^4+20)/(x^2+10x+28).
a.) Find vertical asymptotes? Write the list of x-values of asymptotes separated by commas. If there are none, enter None.
b.) Find x -intercepts and y-intercept. Write the list of x-values of x -intercepts separated by commas.
