Question

What is the domain and range of the quadratic equation y = –3(x – 10)2 + 5?

Answer 1

domain of any polynomial function is all real numbers

Answer 2

the range will be from negative infinity to the y-value of the vertex which is y=5; range is\[(-\infty,5)\]

Answer 3

domain is (-infinity,infinity)

Answer 4

domain is \[\mathbb{R}\]

Answer 5

is it less than or greater than 5

Answer 6

You can include the value y = 5 in the range, so the range is actually \[\Large (-\infty,5]\]
