Find a general expression for the slope of a tangent line to the indicated curve. Then nd the slopes for the given values of x. Sketch the curves and tangent lines. y=x2+3.5x+21r;x= -3,x=2.5 .. ) What is the general expression for the slope of a line tangent to the curve of the function y = X2 + 3.5x + 2:: at the point P(x,y)'? 'T'tan = D (Simplify your answer.) The slope at x = - 3 is D. (Simplify your answer.) The slope at x =2.5 is D. (Simplify your answer.)
