Find the domain and range for the following functions:

Mathematics
1 answer:
Andreyy893 years ago
4 0

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))

f(g(x))=f(\sqrt{x}+1)=\sqrt{x}+1+2=\sqrt{x}+3

Domain would be  [0,∞)

Range would be [3,∞)

d. g(f(x))

g(x+2)=\sqrt{x+2}-1

Domain would be [-2,∞)

Range would be (0,∞)

Multiply the x by 4, then add 3. ( 4×\frac{1}{2}+3= 5 ). Keep doing that for the rest. Hope this helped a little. If you have any questions, you can message me if you would like.
