## Domain Resources x^2/4x-3 what is the domain. I can figure this out

This equation has me stumped, I know that it can not equal zero but that is it. Please help. can someone help and check over the work

Let f(x) = (x - 9)/(x + 2) (a) Calculate f(-3). I got f=-4 for this. or if i didn't finish the entire equation it would be -3f=12 would i finish the equation for this?   f(-3)=(-3)-9/(-3)+2 -3f=-12/(-3)+2 -3f=-12/-1 -3f=12   -3f/-3=12/-3 f=-4   (b)... Birthday Polynomial Project

Task: to create, characterize, graph and present a polynomial function that represents your birthday. my birthday is August 11,1999   I need: Domain and range Y-intercept  Maximum... What is the domain of the tangent function?

I am trying to figure this out, could somebody please help me?    What is the domain of the tangent function? What is the domain of: f(x)= log2(x3-X)   I know how to find the domain of logarithms, but I can't figure out how to treat the x3-x>0. Help please? Given the function h(t)= 3t-1/2t^2-11t+5, find the domain and express your answer in set builder or interval form.

Given the function h(t)= 3t-1/2t^2-11t+5, find the domain and express your answer in set builder or interval form. Find the domain and range of the function

f(x)=   -3x-2     x less than 4 3/4x-1   x greater than or equal to 4   I have figured out the domain is (-infinity,infinity). I am really struggling on... Need help on this word problem.

a bicycilat travels at a constant speed of 12 miles per hour for a total of 45 minutes. (Use set notation for the domain and range of the function that models this situation.)
