Question

#1) What is the domain of f(x) = 5x – 7?

a) x > –7

b) x

c) x

d) x

#2) What is the common ratio of the sequence?

a) -3

b) -2

c) 3

d) 8

Answer 1

#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 .

For #2) Sequence is missing.
