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+22|:;x= 2,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 + 21: at the point P(x,y)? mtan = Cl (Simplify your answer.) The slope at x = - 2 is D. (Simplify your answer.) The slope at x = 2.5 is D. (Simplify your answer.) Sketch the curve y = x2 + 3.5x + 2:: and the line tangent to the curve at x = - 2.
