Step-by-step explanation:
thr standard form for a quadratic equation is:
ax²+bx+c
in this example, a=1, b=(-1), c=(-42)
A reasonable domain and range is the set of values that exist for the function. The sets that are not reasonable are not considered domain and range. For instance, f(x) = 15√(x - 3)
The reasonable domain is {x | R, x ≥ 3} since you can't have negative value inside the radicand.
The reasonable range is {f(x) | R, f(x) ≥ 0} since the minimum value is 0 [Noting that x = 3 gives f(3) = 15√(3 - 3) = 15√0 = 0]
For the $3.75 it would cost $281.25 and for the $3.95 it would cost $296.25
Hope this helps!
Answer: 5/24
Step-by-step explanation:
7/8 = 21/24 2/3= 16/24
21/24 - 16/24 = 5/24
