Answer 1

Answer:

Factors which affect the speed of a reaction are addition of catalyst, temperature, nature of reactants, surface area, and concentration. Explanation: Factors which affect the speed of a reaction are addition of catalyst, temperature, nature of reactants, surface area, and concentration.

Answer 2

Answer:

f(x)=

3x−5

3x−5≥0

⇒ 3x≥5

⇒ x≥

3

5

---- ( 1 )

∴ Domain =[

3

5

,∞)

For range :

y=

3x−5

⇒ y

2

=3x−5

⇒ 3x=5+y

2

⇒ x=

3

5+y

2

But x≥

3

5

[ From ( 1 ) ]

∴

3

5

+

3

y

2

≥

3

5

⇒

3

y

2

≥0

⇒ y

2

≥0

⇒ y≥0

∴ Rage = The real numbers =[0,∞)
