Question 923873: Give the domain and range of h(x) = x^{2} + 9
a) What is the domain of h(x)?
Write your answer in interval notation. If the domain is all real numbers x such that x<-4 then enter (-inf,-4). If the range is all real numbers enter "All real numbers" (no quotes).
b) What is the range of h(x)?
Write your answer in interval notation. If the range is all real numbers y such that y>=9 then enter [9,inf). If the range is all real numbers enter "All real numbers" (no quotes).
how do I get A please thanks

You can put this solution on YOUR website! Re TY
All real numbers can be written: (-inf, inf)
h(x) = x^{2} + 9 Graphically Parabola Opening Upward V(0,9)
a) What is the domain of h(x)? All real numbers
b) What is the range of h(x)? [9,inf)
