Which expression is equivalent to (9x - 3 1/ + 1 3/8)

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β
