it would be positive because whenever you multiple by two negative numbers it turn positive hope it helps
Reflection over the y-axis = change 
Compress by a factor of k = multiply by k
So, in your case, we first change the sign of the argument. Note that this has no effect, because f(x) is symmetric with respect to the y-axis:

Then, we compress the function, multiplying it by the scaling factor:

The product (found when multiplying both numbers together) of 12 and 8 is 96.
The sum (found when adding both numbers together) of 12 and 8 is 20.
The difference (found when subtracting the sum from the product) of 96 and 20 is 76!
Mr. Jones's prescription calls for 1.04 tablets per day. Based on this information, how many tablets should Mr. Jones take per day? a) 1.25 O b) 1.5 c) 1 O d) 2
Answer:
x=5
Step-by-step explanation:
F(x)=-3x+21,
f(x)=6 = -3x+21
6 = -3x+21
Subtract 21 from each side
6-21 = -3x+21-21
-15 = -3x
Divide each side by -3
-15/-3 = -3x/-3
5 = x
