Question

What is the range of the function f(x) = 3x2 6x – 8?

Answer 1

The domain of the function is a real number and the range of the function will be (-11, ∞).

What are domain and range?

The domain means all the possible values of the x and the range means all the possible values of the y.

The function is given below.

f(x) = 3x² + 6x – 8

The range of the function will be

f(x) = 3x² + 6x – 8

f(x) = 3x² + 6x + 3 – 11

f(x) = 3(x² + 2x + 1) – 11

f(x) = 3(x + 1)² – 11

Then the range of the function will be from -11 to infinity.
