Which of the following functions are one-to-one? why or why not?
a.) f(x)= square root 3-x
b.) f(x)= 2x-4
c.) f(x)= x^9 - 8
d.) f(x)= x^6 - 1
e.) f(x)= {x^4 , x-2 if x > or = to 0 & if x < 0
I appreciate the help so I can understand this stuff.
The function f(x)= x^2-4x+7 is not one-to-one. Restrict the domain of f(x) so that the new function with the same formula and restricted domain is one-to-one.
Suppose f(x)=x^2-6x and g(x)= x-6. Find each of the following and specify the domain for each.
a) f+g
b) f-g
c) f (times) g
d) f/g
I don't get how to find the domain or how to write it. I figured out how to find each but not the domain.
Find the domain of the function h(x)= square root of x+1 divided by the square root or x^2+2x-8
that or should be "of"
how do you get all real numbers? and how do you know which sign to use as in < > or <= or =>???
I have a dilemma I don't know how I am going to do this. I was meant to ask the guy I like out this week as its easter and we have 2 weeks off but I did not get the chance as I didn't see him all that much. Hes in the year above me I have his number. We texted most of last year stoped in the...
