Find the domain and range of the function. Use a graphing utility to verify your results. (Enter your answer using interval notation.) f(x) = −x2 − 6x + 7

Question

The question asks to find the domain and range of the function by using interval notation.

Answer 1

Domain and Range of the function f(x)=-x²-6x+7 is the whole real line.

D(f)=(-∞, +∞)= R(f). Draw graph to visualize domain and range.
