You can put this solution on YOUR website! 1.)Given the function k described by k(x)=x+18 find the following: k(0)=?
k(0) = 0+18 = 18
--------------------------
2.)Given the function h described by h(x)=5x, find the following:
h(-16) = 5*-16 = -80
h(15) = 5*15 = 75
h(30) = 5*30 = 150
----------------------------
3.)Find the indicated outputs for f(x)=3x^2-3x
f(0)= 0
--------------
4.)The function H described by H(x)=2.75x+71.48 can be used to predict the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long.
Predict the height of a woman whose humerus is ? cm long.

5.) The function, p(d)=1+ d/33, gives the pressure, in atmospheres (atm), at a depth d in the sea (d is in feet). Note that p(0)=1 atm, p(33)=2, and so on. Find the pressure at 110 feet is ?atm
p(110) = 1 + 110/33 = 4.3333333 atm
-------------------
6.) Graph the function: f(x)=-6x
-------------------
7.) Find the domain of the function: g(x)- 8/8-9x
The denominator cannot be zero.
8-9x = 0 when x 8/9
Domain: All Real Numbers except x = 8/9
--------------------------
8.) Find the domain: p(x)=2x-7
Ans: All Real Numbers
--------------------------
9.) Find the domain of the function: g(x)=4/7-5x
7-5x = 0 when x = 7/5
Ans: All Real Numbers except x = = 7/5
--------------------------
10.)Find the domain of the function: g(x)=9/2-5x
Ans: All Real Numbers except x = 2/5
----------------------------
11.) Find the domain: f(x)=7/|2x-3|
|2x-3| = 0 when x = 3/2
Ans: All Real Numbers except x = 3/2
---------------------
12.) Find the domain: f(x)=3/ |5x-5|
|5x-5| = 0 when x = 1
Ans: All Real Numbers except x = 1
-----------------------
13.) Find the domain of the function: g(x)= 3/ 4-3x
4-3x = 0 when x = 4/3
Ans: All Real Numbers except x = 4/3
----------------
14.) Find the domain of the function: p(x)-x^3-x^2+x-2
Ans: All Real Numbers
