let f be a function such that f(x) = 3x - 2 is defined on the domain 1 is less than or equal to x is less than or equal to 9. th
Anastaziya [24]

Answer:

Range:  [1,25]

Step-by-step explanation:

You may find it easier to express the domain in set notation rather than in words:  [1,9], or 1 ≤ x ≤ 9.  The smallest value of f(x) = 3x - 2 is at x = 1 and is 3(1) - 2, or 1.  The lasrgest value of f(x) is at x = 9 and is 3(9) - 2, or 25.

Thus, the range of this function is [1,25] or 1 ≤ y ≤ 25.
