Answer:

It's odd.

Explanation:

A function is odd when <span><span>f<span>(−x)</span></span>=−<span>f<span>(x)</span></span></span>

<span><span>f<span>(−x)</span></span>=6<span><span>(−x)</span>3</span>−2<span>(−x)</span></span>

<span>=−6<span>x3</span>+2x</span>

<span>=−<span>(6<span>x3</span>−2x)</span></span>

<span>=−<span>f<span>(x)</span></span></span>

Thus, the function is odd.

If a function is odd, then it is symmetric over the x-axis.

M + t = 26
m = t - 6

t - 6 + t = 26
2t - 6 = 26
2t = 26 + 6
2t = 32
t = 32/2
t = 16 <== Trevor has 16

m = t - 6
m = 16 - 6
m = 10...and Marissa has 10

How do i prove 2sec^2x-2sec^2xsin^2-sin^2x-cos^2x=1
kramer
2\sec^2x-2\sec^2x\sin^2x-\sin^2x-\cos^2x=2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)

Since \sin^2x+\cos^2x=1, you have

2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)=2\sec^2x\cos^2x-1

and since \sec x=\dfrac1{\cos x}, you end up with 2-1=1.
