Question

State the domain and range. f(x)=-5(x-1)^(2)+5

Answer 1

X equal all real numbers. Just a sec, I'll graph it to see what values y can take on.

Answer 2

y is less than or equal to 5. It's an upside down parabola with the vertex at 5.

Answer 3

Does the range make sense? y can take on all values less than or equal to 5. Also if you need to graph something, you can always paste it in to google and google will graph it for you.
