Question

Let A = {-2, -1, 0} and f(x) = 2x – 3 then the range of f is​

Answer 1

Solution:

The domain of the function is f(x) is A.

• Substituting the value of A.

when x = 0

↪f(0)= 2 × 0 -3

↪f(0)= 0 -3

↪f(0)= -3

when x = -1

↪f(-1)= 2 × (-1) -3

↪f(-1)= -2 -3

↪f(-1)= -5

when x = -2

↪f(-1)= 2 × (-2) -3

↪f(-1)= -4 -3

↪f(-1)= -7

So the range of f(x) is -7 ≤ f ≤ -3.
