What is the domain of the function f(x)=4x-16?

All real numbers

Step-by-step explanation:

We are given the following function and we are to determine its domain.

For a function, the domain is the set of all input values for which the function is defined to be true.

Here, we cannot have zero as the denominator and neither can we take the square root of a negative number. Therefore, the domain for this function will be all real numbers.

answer:

c. the third graph

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
