<p>I found a mistake on practice test 2, problem 16. </p>

<p>Here is the question.</p>

<p>Which of the following functions will have the greatest value if x= -10?</p>

<p>F. f(x)= x^2 - 2x
G. g(x)= x^2 + 2x
H. h(x)= -x^2
J. j(x)= x^3 - x^2
K. k(x)= x^0</p>

<p>The explanation in the back of the book says the answer should be F. F being 120. One more thing it says is that G equals 80, when in reality it is 100, another mistake! H is -100. Now J obviously is going to be 9900, but in the book it says it comes out to be -1000-100, when it should be 1000-100. I'm no math expert but when you square a negative number it is going to positve so you couldn't get -1000 no matter what. I was just like how the f uck did i get that wrong it was so easy! Overall I got 12 wrong, that's pretty good for me. Did anyone thing that test was easy or are my math skills improving?!</p>

<p>Ummm...</p>

<p>Check again.</p>

<p>A negative to the third power becomes negative again.</p>

<p>im an idiot... going to go kill myself...</p>

<p>F = 120
G = 80 (100 + (2*-10))
H = -100
J = -1100
K = 1</p>

<p>g isn't 100
CC24 caught ur mistake on J.</p>
