Step-by-step explanation:
To evaluate f(- 3) substitute x = - 3 into f(x)
f(- 3) = - (- 3)³ + (- 3)² + (- 3) = - (- 27) + 9 - 3 = 27 + 9 - 3 = 33

Answer:
<h2>
23 cars</h2>
Step-by-step explanation:
total number of cars: x
the total number of axles: 46
and the number of axles installed per car: 2
2 axles in each car, then total instaled axles: 2•x
2•x = 46
x = 46÷2
x = 23
I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
