Varies directly basically means a multiple of
y = kx
where "k" is the constant of variation. You must solve for this first using the given information.
8 = 42k
8/42 = k
0.19= k
Equation: y = 0.19x
when x = 126
y = 0.19(126)
y = 24
Exponential decay is whenever the rate^2<1. So exponential growth occurs whenever r^2>1.
In this case only y=5(4^x) is exponential growth as 4 is greater than 1

Answer:
{-1, 0, 1}
Step-by-step explanation:
If your function is f(x) = 1/2x -2, then the range is found by executing the function on each of the domain values:
f(2) = 2/2 -2 = -1
f(4) = 4/2 -2 = 0
f(6) = 6/2 -2 = 1
The range is {-1, 0, 1}.
