y = x^2 - 4x
To find the slope at (1, -3), we need to first find dy/dx, and then plug in the value x = 1.
dy/dx = 2x - 4
Therefore, for x = 1,
m = 2(1) - 4
m = 2 - 4
m = -2

Your function is extra advantageous written as (a million/2)e^x the factor of tangency is (Ln(3), 3/2) y' = (a million/2)e^x confident, that's the comparable function So the slope of the tangent line at (Ln(3), 3/2) is y = 3x/2 + 3/2(a million - Ln(3))

differentiate:
dy = (x^2 -4x)dx
= 2x-4
set equal to zero and evaluate at x=1
0=2 - 4 = -2
the required slope is -2

Slope = dy/dx = 2x - 4 = 2 . 1 - 4 = - 2
Ans: B
