For what values of x does the graph of f(x) = x − 2 sin xhave a horizontal tangent? (use n as your integer variable. enter your answers as a comma-separated list.)

F'(x)=1-2cosx
Thus to have a horizontal tangent, 1-2cosx=0x=1/3 (-π+6 n π)x=1/3 (+π+6 n π)where n is an integer

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
