I'm currently working through a self taught program, coming up to my first test and have found a review that works well for what I need, I'm stuck on several questions and any help you can provide on any of them will greatly help!(adsbygoogle = window.adsbygoogle || []).push({});

1. Consider the function: y = x^2 - 2x - 8

a) State the equation of the reciprocal function

b) Write the equation of the vertical asymptotes (I find this to be a parabola which can't have asymptotes which is my struggle)

2. If "a" is an angle in Quadrant 4 where cos a = 4/5, and "b" in an angle with sinb= 12/13 where 90 degrees< b < 180 degrees.

a) What is the exact value of sin(a+b)?

Any help you can provide or links to pages or videos will greatly help! Thank you!
