Answer:

Both the domain and range are the set of all real numbers. For the absolute value function f(x)=|x| f ( x ) = | x | , there is no restriction on x . ... For the cubic function f(x)=x3 f ( x ) = x 3 , the domain is all real numbers because the horizontal extent of the graph is the whole real number line. this is the best i can do if its not helpful i guess u can ask ur teacher.

Let d(t) be the total number of miles Joanna has cycled, and let t represent the number of hours after stopping for a break duri

katrin [286]

For this case we have the following equation:
$d (t) = 12t + 20
$
The variables are:
t: time in hours
d (t): distance traveled in miles.
We evaluate the distance traveled after 4 hours.
So we have that for t = 4:
$d (4) = 12 (4) +20

d (4) = 48 + 20

d (4) = 68$
Answer:
d (4) = 68
This means that after 4 hours Joanna cycled for 68 miles total

Answer:

a. Total field goal points scored in the first two quarters, in simplest linear expression form is: 3x - 4.

b. The total points scored in the game, in simplest linear expression form is: 6x - 1.

a. The goal points scored in the first two quarters are expressed in linear forms as: 2x - 6 and x + 2.

The total field goal points in the first two quarters = 2x - 6 + x + 2
