Tangent Lines
Find the equation of the line tangent to the graph of h(x)=5x^(3)-10x^(2)+20 at x=2 (answer has to be in slope intercept form)

Slope intercept form is y=mx+b.
You are given x. For y, plug x=2 into h(x). To find m, differentiate h(x) and plug in x=2. Then, you have the slope at that point. Plug all this into y=mx+b and solve for b. You're done. |

Hi there, How would I solve this? A tangent to the hyperbola y=1/(2x) , x>0 cuts the y- axis at the point y=2 Find the gradient of this tangent? If I differentiate the hyperbola, I would get -1/(2x^2) and then I don't know how to go on about doing it. Thanks
Hi everyone, Okay, it was my suggestion to start a different post so that we can stop second guessing ourselves on the "Is my boyfriend cheap" post, so I guess I'm stuck following up on it. I'm going to try and be as specific about this as I can, but since this is not based on an actual ...
Show that the tangent line to the curve y = x^3 at the point x=a also hits the curve at the point x = -2a. Can anyone tell me if I'm on the right path? I set the function and the slope of a line secant to the functions through the points (a, f(a)) and (-2a, f(-2a)) equal to each other and...
