Which statement is true about the discontinuation of the function f(x)? f(x)=x+1/6x^2-7x-3

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
