Question 156686: The problem is: Evaluate and find the domain. f(x)=1/x^2-9 for x=4,a-5
I am able to evaluate and came up with f(4)=1/7 and f(4)=1/a^2-10a+16. What I don't understand is how to find the domain. I know my book says the answer is: x is not equal to 3, and x is not equal to -3. I just don't know how the domain came to be this, I don't understand how to find the domain. Please help.

Question 157663: Alright, I've got one last question. I keep getting half of what the book says the answer is. It seems like such a simple problem, but for some reason I just can't get an answer that matches the books! It's a word problem:
Harold Johnson lives on a four-sided, 50,000-square-foot lot that is bounded on two sides by parallel streets. The city has assessed him $1,000 for curb repair, $2 for each foot of property bordering on these two streets. How far apart are the streets?

Question 157686: Hi, can you please help, can you please help with this piecewise defined function
.
Piecewise defined function
.
f(x) = { x - 4, +x+%3C=+2+ }
.........{ 2x + 3, +2+%3C+x+%3C=+14+ }
.........{ 36, +x+%3E+14+ }
.
I think the domain is ( +-+infinity+,+%2B+infinity+ )
.
I think the range is ( +-+infinity+, +-2+ ] U ( +7+, +31+ ] U { +36+ }
.
Is this domain, and range right? Can you please confirm? Please use interval notation, just like what I used for the domain and range
.
Thanks ahead of time, Levi
