Given f(x)=x^2-8 and g(x)=x+1/x, find (g o f)(1)
[hint: (g o )=(g(f(-4))]
a.)8/7 b.)8 c.)6/7

F(1) is equal to 1^2-8, or -7.

g(x) is (-7+1)/-7, or -6/-7.  This simplifies to 6/7.  C is the best option.

Also, since you posted a similar question earlier, I knew what to look for with g(x), but in the future, this looks like the x is not divided by the x in the denominator, and you should express this function as (x+1)/x to increase clarity.

She should use 12/3 to measure
