consider the function f(x)=9/x and g(x)=9/x find f(g)x))and any values that may be excluded what is g(f(x)) and any values that may be excluded and functions f and g inverse of eachother

college Alg
graph the parabola, then determine the domain and range. f(x)=x^2x-4x-4

college alg
the function f(x)=6x+9/3x-7 find the inverse and check answer f^-1(x)=? please show work

college algebra
solve the following exponential equation. (e^x-e^-x)/2=6 what is the exact answer? x=? what is the answer approx to 3 decimal places? x=?

college algebra
solve the following logarithm equation log (4x+7)=1+log(x-6) x=? please show work

college algebra
so do i write the domain as (-infinity,infinity) not sure how to write the range you showed. It has to be in interval notation would it be (infinity,-8)?

college alg
for the given functions f and g find the following and state the domain of each result f(x)=3x+1/8x-9; g(x)=5x/8x-9 (they look like fractions) A) (f+g)(x)=? B)domain of (f+g) c) (f/g)(x)=? d) domain of f/g? please show work

college alg
find the equation of a line that is perpendicular to line y=1/6x+6 and contains point (-7,0) y=? please show work so i can see how its done

college alg
find the equation of a line that is parallel to the line x=6 and contains the point (-8,9) please show work, it also wants me to show the answer in an equation
