Consider the function f(x)=2x+58x+5.For this function there are two important intervals: (-,A) and (A,) where the function is not defined atA.Find A.Find an equation for the horizontal asymptote off(x).y=Find an equation for the vertical asymptote off(x).x=For each of the following intervals, tell whether f(x)is increasing (typein INC)or decreasing (typein DEC).(-,A):(A,):Note that this function has no inflection points, but we can still consider its concavity. For each of the following intervals, tell whether f(x)isconcave up(typeinCU)or concave down (typeinCD).(-,A):(A,):
