Question

Find domainf(x)=3√(x-1) +2

Answer 1

f(x)=3√(x-1) +2

The domain of a function is the set of all possible x values.

Since the function doesn't have a denominator but has a square root:

the number under the square root can't be negative:

x-1 ≥0

Solve for x:

x≥1

Domain: all real numbers, where x≥1
