y = 5×3 – 2×2 + x + 3
y’ = 15x^2 – 4x + 1
When x = -1:
y’ = 15 + 4 + 1
= 20
The tangent is therefore:
y – (-5) = 20(x – (-1))
y + 5 = 20x + 20
y = 20x + 15.

keep in mind that the by-manufactured from a function is the SLOPE of the tangent line. so plug in pi/3 in y’= -sinx y’= -sin(pi/3) =sqrt(3)/2 ^slope of tangent line then plug in pi/3 into the unique equation to locate the y-coordinate of the element the place the tangent line touches the graph. y=cos(pi/3) y=a million/2 the equation of the tangent line in element-slope form could be: y – a million/2 = sqrt(3)/2 (x – pi/3) desire that enables!
