HELP ASAP ALGEBRA 2 QUESTION PLEASE!!!
vesna_86 [32]
a)
f(x) is the same as y
y=1/3 x +4

<span>to find inverse, swap and x and y:
x=1/3 y + 4
x-4= 1/3 y
(x-4) x 3 = y
3x -12= y
                       the inverse(g(x)), is: 3x-12

b) </span><span>if f(x) and g(x) are inverses of each other, than </span><span><span> (f<span> о </span><span>g)(x)</span></span> will end up with just "x"
</span>
<span>(f о <span>g)(x)=x
</span></span><span>(f о <span>g)(x)= f(g(x))
</span></span><span>(f о <span>g)(x)= f(3x-12)
</span></span><span>(f о <span>g)(x)= 1/3(3x-12)+4
</span></span><span>(f о <span>g)(x)= (3x-12)/3  +4
</span></span><span>(f о <span>g)(x)= x-4+4
</span></span><span>(f о <span>g)(x)= x

</span></span>c)
<span>You will find that the graphs are mirror images of each other </span>
the graph for f(x) is an oblique line that passes through the points(-12,4)
the graph for g(x) is an oblique line that passes through the points(4,-12)

standard deviation = square root of the mean deviation of each value

then deduct the mean from each element

and square each value and add them together. not you should square each deviation value before you add them

at last divide the result by the number of frequency and find it's square root
