Find the domain and range for the following functions:
a. f: ℝ → ℝ given by f(x) = x2
b. g: ℝ → ℝ given by g(x) = √x − 2
c. f(g(x))
d. g(f(x)) = g(x2) = √x2 − 2

awnser choices please?

Step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
