#1) what is the domain of f(x) = 5x – 7? a) {x | x > –7} b) {x | x < –7} c) {x | x > 0} d) {x | x is a real number} #2) what is the common ratio of the sequence? a) -3 b) -2 c) 3 d) 8

#1) Domain is the set of values of x at which the function is defined.

The given function is f(x) = 5x – 7 a linear function.

There is no restriction for a linear function because a linear function is define at every values of x.

Therefore, domain of all linear function is all real numbers.

Therefore the correct choice is d) {x | x is a real number}.

For #2) Sequence is missing.

answer is  

minor arc – sw

major arc – stu

semicircle – wst

i got it down chief.
