Find the equation of the tangent line for the graph y = (4x)^2 + 3 at the point (1,8)
y = (4x)^2 + 3 = 16x^2 + 3
y' = 32x
As stated before, the point (1,8) is not on the function, but . . .
for x = 1, m = y'(1) = 32, and y = 19
Point-slope equation: y - 19 = 32(x - 1)
Equation for the tangent line of the given function at (1,19) is y = 32x - 13
Disclaimer: I haven't taken a math class since the nineties, so . . .
