## Functions Resources i am completely lost on what steps to take for this. I have a ti-84 calculator for equations, etc if needed. thanks in advance When substituting a variable in a term with an exponent, how do I write and solve it?

IE: -2x^2 Do I do: -2(x)^2, -2(x^2) or (-2x)^2 I say this because of a problem I have that says "h(x)=-4x^2 -2x+5"

I am unsure of how to do this problem or even set it up. I didn't know whether to find the slope of the two points or not and was wondering if one of you all could help me. I would really appreciate...

I'm very stuck on this question and I'm not sure how to graph this function. Demonstration for one-to-one function

Show that f is a function one-to-one, if and only if f(x) = 0 for x=0. I cannot solve this demonstration, I know that if both elements are the same and their functions are the same, then is one... Graph the relation. Is the relation a function? Why or why not? {(-1, 1), (-2, 1), (-2, 2), (0, 2)}

Graph the relation. Is the relation a function? Why or why not? {(-1, 1), (-2, 1), (-2, 2), (0, 2)} Domain and Range

A=((450-3x)/2))w   Determine the domain and range of this area function. Determine the dimensions that give the maximum area. Please help me solve this step by step. Function Notation

As a mental arithmetic exercise, a teacher asked her students to think of a number, triple it, and subtract the resulting number from 24. Finally, they were asked to multiply the resulting difference... Function Notation

For f(x)=1/2x, determine f(1)-f(3). I want to know how to do this step by step.
