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,∞)

The measure of angle θ is 600°. <br> The point (x, y) corresponding to θ on the unit circle is (
Grace [21]
On the unit circle the hypotenuse is always one so we can say:

sinα=y/1 and cosα=x/1 so

The point corresponding the the angle 600° is:

(cos600, sin600) which is approximately

(-1/2, -√(3/4)

Rewrite the function to make it easy to graph using transformation of its parent function. Describe the graph. y = squ(25x - 25)
Mariana [72]
Parent function is y=√x
result is
-4+√(25(x-1))

-4 was added to whole function so translated 4 units down
it every x was multipied by 25  so horizontally stretched bya factor of 25
then, minus 1 from every x to move to right

so the blanks are
strech 25, 1 to the right, 4 down
