The following problem ustrates this The inverse notation used in a pure mathematics problem is not always when finding i s of pplied problems. Rather the inverse of a function such as C Under certain conditions. If a rock falls from a height of 110 meters he t me e r onds is approximated by the following equation HU)= 110 -4.912 (a) in general, quadratic functions are not one-to-one However the function is one-to-one Why Choose the correct answer below The coeficient of it is negative, so the function is always decreasing A decreasing action is always one-to-one The parabola opens to the night, so passes the horizontal line to Thus. H is one-to-one The term is not the first terms ) does yo behave the datinction O represents time, so must be greater than or equal to 0 Forta, is one to one () Find the inverse of Hand verify your result 10 0 45 Type an exac er) (c) How long will take a rock to fall 60 meters?
