Answer:
D) -122
Step-by-step explanation:
Given:

We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;

By using PEDMAS we will solve for exponential function first we get;
Now we know that 
So we get;

Now using PEDMAS we will solve division.

Now using PEDMAS we solve multiplication.

Finally by subtraction we get;

No, i don't think it's true
The answer is 75! Explanation: Use the distance formula:)
In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60.
Good luck :D
