Put the value of x = 3 to the equation of the function h(x)


h(x)=x-1\\\\h(3)=3-1=2


Put the value of h(3) = 2 to the equation of the function g(x)


g(x)=3x-5\\\\g(2)=3\cdot2-5=6-5=1


Put the value of g(2) = 1 to the equation of the function f(x)


f(x)=-2x^3\\\\f(1)=-2\cdot1^3=-2\cdot1=-2


Answer: -2

Suzie paid a total of $324 dollar sign, 324 for x tickets to a rock festival.
MA_775_DIABLO [31]

Find the ticket unit cost:  divide the total paid, $324, by the number of tickets, x.  Then the form of the unit cost is

$324

--------- .

   x

This question is highly unusual in that you write "x" as the number of tickets sold, instead of a specific number of tickets.  Supposing that you'd sold 100 tickets for $324, then the unit cost would be, much more typically, a numeric ratio:

$324

----------------- = $3.24/ticket

100 tickets
