it is a beautiful day at the fair. the u.v. index for the day is 8, or high, so sunscreen is a must for young folk. the effectiveness is indicated by the sunscreen protection factor (SPF). the higher the SPF number the fewer u.v. rays can penetrate to burn the skin. when the protection factor (SPF), s, is known you can determine the percent,p, of the suns u.v. rays that pass through it by using the following model
a/ what are the asymptotes of the function? someone determined both horizontal and vertical were 0, but what does that mean in the context of this problem?
b/ how would i graph this?
c/ figure out the percent when SPF=35 so 100/35=2.8%..?
