Question 1000678
I need help with this problem please:
Find the equation of the tangent line which can be drawn to the graph of {{{y = 2x^2}}} at the point (1,2)
-------------
The slope is the 1st derivative.
{{{y = 2x^2}}}
y' = 4x
At x=1, m = y' = 4
--------------
y-2 = 4(x-1) is the tangent line.
y = 4x - 2
