Question

Please help :( can you explain and write the answer

Answer 1

f(x)=x-2

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),x|x ∈R}(-∞,∞),x ∈R

Range: (−∞,∞),y∈R

g(x)=x^2-3x+2

Domain: (−∞,∞),x ∈R(-∞,∞),x

Range: [−1/4,∞),{y∣y≥−1/4}
