Find the domain and range of the function below. y = 3x2 - 6x + 5 a. d: all real numbers r : (22) d: all real numbers r: ( 32) c. d: ( x2) r: all real numbers d: all real numbers r: all real numbers

ANSWER

Domain: All real numbers

Range:

EXPLANATION

The given function is

To find the domain and range of the given function, we complete the square.

The vertex is at (1,2).

The given function is a polynomial and all polynomial functions are defined everywhere.

The domain is all real numbers.

The parabola opens upwards and have vertex at (1,2). Hence the minimum y-value is 2.

The range is

is it 35
