Question

Find range of f(x)=2-3x, x belongs to R, x>0.​

Answer 1

Question :-

• Find range of f(x) = 2 - 3x, x belongs to R, x > 0.

Solution :-

$\bf \:As \: x > 0$

Multiply by 3 on both sides, we get

$\bf\implies \:3x > 0$

Multiply by - 1 on both sides, we get

$\bf\implies \: - 3x < 0$

Adding 2 in each term, we get

$\bf\implies \:2 - 3x < 2$

$\bf\implies \:f(x) < 2$

$\bf\implies \:f(x) \: ∈ \: (- ∞, 2)$
