Question

What is the domain and range of f(x)=4 x 2 to the x power

Answer 1

• domain: all real numbers
• range: all positive real numbers

Explanation:

The function is defined for all values of x, so the domain is all real numbers.

An exponential function has a horizontal asymptote at y=0. Multiplying it by 4 doesn't change that. The value cannot be zero, and it cannot be negative. The range is all positive real numbers.
