Consider the function. f(x) = x2 + 3 Which answer pairs a possible domain restriction for f(x) and its corresponding impact on f–1(x)? f(x) domain: x ≥ 3 f–1(x) domain: x ≥ 3 f(x) domain: x ≥ 3 f–1(x) range: y ≥ 3 f(x) domain: x ≥ 0 f–1(x) domain: x ≥ 0 f(x) domain: x ≥ 0 f–1(x) range: y ≥ 0

The answers is: f(x) domain: x ≥ 0

                          f–1(x) range: y ≥ 0

Step-by-step explanation:

By restricting the domain of f(x) by x ≥ 0 you can now have an inverse function for  f(x) = x2 + 3. Also the domain of f(x) is equal to the range of  f–1(x).

D

f(x) domain: x ≥ 0

f–1(x) range: y ≥ 0

Step-by-step explanation:

b

step-by-step explanation:

ez

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
