The grams of weight W gained each day by a snake x days after it's birth can be modeled using function W(x)=0.5 +0.7 ln (x). First question what is the domain of function, if the function is only valid during through first 12 days? Second question use the function to find the weight gained on the 8th day after birth? Third question one what day will the weight gain reach 1.65 g? Please explain steps by step. I have no idea how to do this problem
