<span>This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0.
If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.</span>
Answer:
$2.35
Step-by-step explanation:
Nickels are worth 5 cents each and quarters are worth 25 cents.
7 nickels = 7 * 5 cents = 35 cents
8 quarters = 8 * 25 cents = 200 cents
Total = 200 + 35 = 235 cents
There are 100 cents per dollar, so we can find the dollar value by:
235/100 = $2.35
