What is the domain of the function y = 3√x

Answer is A.) -infinity, infinity

{x | x ≥ 0}

Step-by-step explanation:

We have the function, .

Now, for the square root function, the values inside the square root must be positive.

Here, we have that the values of 'x' must be greater than or equal to 0.

i.e. x ≥ 0.

Hence, the domain of the function is {x | x ≥ 0}.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
