If {3,4,5} is the domain of function f:x --> 2x-1, find the range. ​

Range = {5, 7, 9}

Step-by-step explanation:

Range is the set of values that are the results of respective values of x when placed in the function f(x).

f(3) = 2 × 3 - 1

f(3) = 6 - 1

f(3) = 5

f(4) = 2 × 4- 1

f(4) = 8 - 1

f(4) = 7

f(5) = 2× 5 - 1

f(5) = 10 - 1

f(5) = 9

Therefore, the range is the set of all these values :-

Range = {5, 7, 9}

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
