Question

Let f be a function such that f(x)= 3x -2 is defined on the domain 1< x <9 the range of this function is

Answer 1

The range of this function from 1
1

Answer 2

Range is a set of all the y-values of a function. To find the range, substitute the minimum x-value (1) and substitute the maximum x-value (9) into the function. Since the signs for the domain are “<“ and “>”, the same signs will be used for range. The range for f(x) is 1< y< 25
