trigonometry
find the grahp of cos(x-2) first and then switch your x and y value, oh another thing with arc cos you have to limit it from one point to another or else its not a function anymore, so say a regular cos has 2pi for its period dont graph that whole 2pi for the arccos graph one ...

trigonometry
its jsut a regular sec graph but you move everything pi/2 to the left

trigonometry
its a regular tangent graph but you move everything over pi/2 to the right

trigonometry
your period is pi i got that by dividing 2pi(which is the regular period for cos and sine) by 2 and then you move everything up 2 and to the right pi

algebra
you just plug in 1.7 for N and isolate the x to get the year 1.7mil= 0.05x - 98.45 its simple algebraic manipulation. you move 98.45 to other side by adding it to both side leavign you with 1.7 mil + 98.45= 0.05x and then divide both side by 0.05 to get x by itself imma assume...

math
cube everything in the parenthesis and you get 8x^3 cube the 2 and you get 8 so you you get 8x^3 + 8x factor out 8x 8x (x^2 +1)

is this what the problem looks like: (( 3n)^2 - (n/n^2) - 1)/ (n^2 / n+1)?
