So the first 3 were "yes" and the last one was the only one that was "no"?

So the first 3 were "yes" and the last one was the only one that was "no"?

If the rational root must = x, then this the accurate solution:

a=1000; x=1; b = sqrt(a - sqrt(a + x));if(b==x, goto loop,0);x++;if(x<1000, goto2, 0);a=a+1;x=1;if(a<2000, goto2,0);loop: printb, x, a

Where a =1,057, x =32, and the rational root =32

(f - g) (x)   =

f(x) - g(x)  =

[ x^4 - x^2 + 9 ] - [ x^3 + 3x^2 + 12]  =

x^4  - x^2 + 9  - x^3 - 3x^2 - 12  =

x^4 - x^3 - 4x^2  - 3

We have more than just integers and whole numbers involved....these do not account for partial seconds....so....

[ 0, 5 ]

Increasing on (-inf, -6) , ( -3, 2)  and ( 6, inf)

Decreasing on  ( -6, -3) and ( 2, 6)

We have the form

y = Asin (Bx)  + C

A = the amplitude  = 2

Frequency  =  1 /period

1 / (4pi)  =  1 /period

So...the period = 4pi

So

B  =  2pi / [ period]   =   2pi / [ 4pi]  =  2 / 4    =  1 / 2

C = the shift up/down....since we have a y int of (0,2)....the normal sine function is shifted up 2 units....so C = 2

So....the function is

y = 2sin ( (1/2) x) + 2

Odd

To see why....if   

f(-x)  = - f(x)   it is odd

So....let x = 1/2

f(-1/2) ≈  2

-f(1/2) = - (-2)  ≈  2

So

f(-x)  = - f(x)

If   f(x)  =  f(-x)   ⇒  even

If   f((-x) = -f(x)  ⇒  odd

Else...neither

So

f(x)  =  x^6 - x^4

f(-x)  = (-x)^6 - (-x)^4     =  x^6  -  x^4   =  f(x)  ....so even

f(x) = x^5 - x^(4)......neiher even nor odd because

f(-x)  = (-x)^5 - (-x)^4  =  -x^5 - x^4     .....not equal to f(x)

-f(x)  = - [ x^5 - x^4]  =  -x^5 + x^4......not equal to f(-x)

f(x)  =  x^5 - x^4

f(-x)  = (-x)^5 - (-x)^3  =  -x^5 + x^3.....not = to f(x)....so....not even

-f(x)  =  - [ x^5 - x^3 ]  =  -x^5 + x^3   =  f(-x).....so....odd

Thank you everyone for your help! Looks like we got it figured out and no, the x was not a variable. The rules were you could move around numbers and symbols but not the answer (75).

Age - 3.9

________    = -1.7          multiply  both sides by 1.2

     1.2

Age - 3.9  = -2.04       add .09 to both sides

Age  =  1.86

[ 106 -  100]                6

__________  =        ____  =    1.3

     4.6                       4.6

[ 75 - 70 ]                   5

________    =          ___  =    2.08

     2.4                      2.4 

So

Felix’s Z score on the amplitude test was 1.30. His Z score on the knowledge test was 2.08. Felix performed  better on the knowledge test, comparatively.

BTW.....I think it is "aptitude", not "amplitude"

Gah i just got logged off i didnt do that

Hes being hacked

Well thats not rude but yes i agree

A negative z-score is BELOW the mean

3.9 -1.7 x 1.2 =  1.86 yrs

He knows. Theres more the story but nvm.
