k, so im stupid, n i got a graded assignment.....so help? oh, i also need to show the work....but if u dont show the work, answers are fine too, i can do it from there...
1. let f be the function given by f(x)=(2x-5)/(x^2-4)
a. find domain of f
b. find f '(x)
c. write an equation for the line tangent to the graph of f at the point (0,f(0)
2. let f be the function defined by f(x)=7-15x+9x^2-x^3 for all real numbers x
a. find the zeros of f
b. write an equation of the line tangent to the graph of f at x=2
3. let f be the function given by f(x) = (x^4-16x^2)^(1/2)
a. find the domain of f
b. describe the symmetry, if any, of the graph of f
c. find f '(x)
d. find the slope of the line normal to the graph of f at x=5
4. let f be the function given by f(x)= x/((x^2-4)^(1/2))
a. find domain of f
b. find f '(x)
c. find equation of the tangent line when x=4
5. let f(x)=(1-sin x)^(1/2)
a. what is domain of f?
b. find f(x)
c. what is domain of f '?
d. write an equation for the line tangent to the graph of f at x=0
6. let f be the function defined by f(x)=(x+sin x)/(cos x) for -[pi]/2<x<[pi]/2
a. state whether f is an even function or an odd function. justify your answer
b. find f '(x)
c. write equation of line tangent to graph of f at the point where x=0
yes, [pi] in problem 6 is the number pi......any help would be greatly appreciated
