Answer:

-9

Step-by-step explanation:

The problem can be easily solved if you know your cube table. Because by knowing that, you know that 9³ is 729, meaning that -9³ would be -729.

Without knowing your cube tables, you can do -9 x -9 x -9 = -729.

Since -9 x -9 = 81, you can use a calcuator or solve on paper for 81 x -729.

What is the range of the function f (x)=3.2x for the domain (-4, -2, 0, 2, 4)?

Aneli [31]

So we don't have to multiply each domain, we just need to find the lowest and highest domain and put it into the equation (since we're just multiplying)
-4 and 4 are the lowest and highest.
3.2×-4=-12.8; this means that when 4 is put into the equation, it will be 12.8 since they're opposites.
So, the range is -12.8 to 12.8.
