Answer with Step-by-step explanation:
Since we have given that
a. f: ℝ → ℝ given by f(x) = x + 2
Domain would be all real numbers i.e. (-∞, ∞)
Range would be all real numbers i.e. (-∞, ∞)
b. g: ℝ → ℝ given by g(x) = √x − 1
Domain would be all positive numbers i.e. [0,∞)
Range would be [-1,∞)
c. f(g(x))
Domain would be [0,∞)
Range would be [3,∞)
d. g(f(x))
Domain would be [-2,∞)
Range would be (0,∞)
Answer:
3. 2.4 c.m
The height of the cone 'h' = 2.4 c.m
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Given radius of the cone = 2 cm</em>
Given data
The volume of a cone-shaped dessert is 10 cubic centimetres
<em>The Volume of the Cone </em>
<em> </em><em></em>
cross multiplication , we get
h = 2.388 ≅ 2.4 c.m
<em>The height of the cone 'h' = 2.4 c.m</em>
