(a) find the slope m of the tangent to the curve y = 5 + 5x2 − 2x3 at the point where x = a. m = (b) find equations of the tangent lines at the points (1, 8) and (2, 9). y(x) = (at the point (1, 8)) y(x) = (at the point (2, 9))

The slope of the tangent will be "". The equation at point (1, 8) is "" and at point (2,9) is "".

Given equation is:

(a)

The slope of the tangent to the curve point where is:

→

→              

(b)
