What are the domain and range of the function f(x) = 3x + 5? domain: (negative infinity, infinity); range: (0, infinity) domain:

AlekseyPX

Answer:

Domain : (-∞,∞) Range : (-∞,∞)

Step-by-step explanation:

Given:

f(x) = 3x+5

To find: Domain and Range of f(x)

Domain is the set of values that x can take.

Range is the set of values of y corresponding to the values of x in the domain.

Here x can take any value and the domain is the set of real numbers i.e (-∞,∞).

f(x) = 3x + 5

The graph of f(x) is a straight line that extends from -∞ to +∞ and hence the range is (-∞,∞).

At Sam's birthday lunch, Sam and one of her friends each ordered a $4 salad while her other 4 friends each ordered a $6 sandwich

Brrunno [24]

Each person will pay $7 before taxes and tip.

Step-by-step explanation:

Price of salad = $4

Price of two salads = 4*2 =$8

Price of sandwich = $6

As 4 friends ordered sandwiches, therefore,

Price of 4 sandwiches = 6*4 = $24

Price of slice of cake = $3

Total = 2 salads + 4 sandwiches + 1 slice of cake

$Total = 8+24+3$

$Total = $35$

5 friends will split the bill evenly, therefore,

Bill for one person = $\frac{Total\ bill}{No.\ of\ people\ paying}$

Bill for one person = $\frac{35}{5} = \$7$

Each person will pay $7 before taxes and tip.
