- Correct. The range of all linear functions without a restricted domain is the set of all real numbers.
- Wrong. The exponential cannot take negative values.
- Wrong. Quadratics do not have a range that is the set of real numbers.
- Wrong. Quadratics do not have a range that is the set of real numbers.
If the rate is 60 pounds for $6.60 and we need to convert it to a unit rate per ounce, you will think of it as $6.60 for 60 pounds instead.
Divide to get a unit rate per pound.
$0.11 per pound
To convert this to an amount per ounce Change the rate to say $0.11 per 16 ounces(this means the same).
Divide 0.11 by 16 to get 0.006875 or $0.007 or 0.7 cents per ounce. Choice D but it should say per ounce, not per pound.

Hi
5x²-x-4 = 0
Δ= (-1)² - 4*5*(-4)
Δ = 1 -4*-20
Δ = 1 +80
Δ = 81
√Δ= 9
as Δ ≥ 0 , so 2 solutions exist in R
S1 is : ( 1+9) /2*5 = 10/10 = 1
s2 = (1 -9)/2*5 = -8/10 = -4*2 /2*5 = -4/5
Corrects answers are A and D
