Find an equation of the tangent line to the graph of f(x) = -1/x at a) (-1,1); b) (2, -1/2); c) (-5, 1/5)

Ive had success with completing similar problems but I am having a lot of trouble getting a simplified difference quotient since the given component (-1/x) is negative. How does it simplify and what a

Calc help!! DERIVATIVES

Thanks for looking at my question!! I really appreciate it. Given the following data for a function f: x:1.11.31.51.71.92.1 f(x):121521232425 Estimate f (1.7). The answer should be around 7.5, I

I cant solve this question. the answer is supposed to be 10.6 but i keep getting 17. Could someone please help? 7+3 / 5 x 6 between the 3 and the 5 is a division sign not a fraction. Thanks-Use PEMDA

Solve x^2 + 2x + 9 = 0

Help!-Hello, this one is kind of painul because it involves a complex number solution... First, its simplest to just complete the square...(Or use the quadratic method above) We note that (x+1)(x+1

Find y in terms of x if dy/dx=x^6y^-5 and y(0)=6

Any help cant seem to get it-dy/dx = x^6y^-5 Separate the variables. y^5dy = x^6dx Integrate. (1/6)y^6 = (1/7)x^7 + constant When x=0, y=6 so the constant is 6^5, thats 7776. (1/6)y^6 = (1/7)x^7 + 777

How do you solve an absolute value equation

I need to know because I have a test in 2 days and I have no idea how. Here are some examples. |x+3|=5 |3x-2|=8 |1/2t-4|=1 |1-2/3x|=9-when you do absolute values, you have to copy down the original qu

Can someone Factor this please

2x^2+5x-3-(2x -1 )(x + 3)-The formula to factor a quadratic functiony = ax^2 + bx + c is: Find the roots... x1and x1and write:y = a(x-x1)(x-x2) In you case the roots are -3 and 1/2then we factor so:

Help with induction question

Use mathematical induction to prove the property for all positive integers n. For the equation: [a^n]^5=a^(5n) This makes no sense to me at all.-First show that it is true for n=1. [a^1]^5 = a^5 a^(

Implicit differentiation... find dy/dx for tan(x +y)=y

i know that sec^2(x+y)( dx/dx - dy/dx)= dy/dx sec^2(x+y)(1- dy/dx)= dy/dx but what do i do from there? help please :)-sec²(x + y)(1 + y) = y sec²(x + y) + ysec²(x + y) = y sec²(x + y) = y - ysec²(x
