Determine whether y is a function of x x2 + y2 = 16

A rectangular parcel of land has width, w feet. The length of the diagonal, d, between opposite corners is 18 feet more than the length of the parcel. Note that d is lowercase. (a) Express the length, L, of the parcel as a function of d. (b) Express the width, w, of the parcel as a function of d. (c) Express the area, A, of the parcel as a function of d. L = W = A = (d) Suppose a fence is to be built around the perimeter of the rectangular parcel of land. The fencing material will cost $25 per foot. Express the total cost, C, of fencing the parcel as a function of d. C =

3. Determine the domain and range of the function y = 2c0sx

given the function y=4logb(x+b^5)+3b, where b is some positive constant, which of the following represents its y-intercept

Identify the relations which are also functions.

RyAnne has 8 coins and decided to begin a collection.    On the first day of collecting, she has 32 total coins in her collection    On the second day of collecting, she has 128 total coins in her collection   On the third day of collecting, she has 512 total coins in her collection Write a function that represents the number of coins as a function of the number of days, x.

A 1000-square-foot rectangular plot of land is going to be divided into three equal-sized, adjacent playgrounds (see diagram). Find the number of feet of fencing required as a function of x. (Note: there is only one fence between the playgrounds, not two.) Answer:

write the given function as piecewise defined function, y=|x-2|+3
