The derivative tells you the slope at any point. df/dx = 8 x^3 - 12 x When x = 3, the slope is m = 8*27 - 36 = 180 and the equation of the tangent line is (y - 228) = 180*(x - 3) y = 180 x - 540 + 228 = 180 x - 312 wow, that was absolutely correct (i just plugged it into ...

What is the equation for the line of symmetry for the graph of this function? function y = x2 - 4x - 5, if you have a graphing calulator you can put it in there, or just graph it on a piece of paper using a T chart. find it by one of those.

Do you want the equation of a line through that point (1,2) with slope m = 4? Use the equation (y-y*) = m(x - x*) where x* and y* are the coordinates of the point the line has to pass through. (1,2)m=4

Find the equation of the line passing through the points: (-5,-5) and (6,-5) Hmmm. both y are -5. The line has to have zero slope, and the y intercept is -5 y= -5 is the equation Thank You

First the slope. Perpendicular to a slope of -3 means a line slope of 1/3 y= 1/3 x + b. Now put in the x,y point and solve for b. write the equation of a line that has a y intercept (0,5) and is perpendicular to the line with equation y=-3x+1

calculus totally confused
find a first degree polynomial function p(1) whose value and slope agree with the value and slope of f at x=c. i think you use taylor series for this f(x)=4/sqrt(x), c=1 i'm totally confused on how to do it. i know you find the derivative but how do i get the function. this is...

write an equation for the line through the given points or through the given point with the given slope (5,7),(6,8) (1,2),(3,8) (0,5),(-3,2) (8,11),(6,16) For each of them, use the standard formula (y- y1) = [(y2-y1)/x2-x1)]*(x-x1) In the first case, that gives you (y-7) = (1/...

Wrtie an equation of a line passing through (6,10) and (6,-6 y= mx + b Put in the first set of points: 10=6m + b Do the same for the second point. Then, you have two equations, two unknowns. Solve by substitution.

I need help with this question. Write the equation of the line which contains the point)0, -3) and whose slope is 4. A general line equation can be written as y = mx + c, where m is the slope and c a constant. so we can write this as y = 4x + c Substituting the point (0, -3) ...
