Question 1090061: The question asks:
The tangent line intersects the graph of�f(x)=2x^3+10x^2−28x�at another point. Determine the other point of intersection. I have already found my tangent line eq'n y=-34x+18 @ �= -3. I substituted and factored :
-34x+18=2x^3+10x^2-28x=0
2x^3+10x^2+6x-18=0
2(x^3+5x^2+3x-9)=0
2(x-1)(x+3)^2=0
I know that my x-axis is 1, how do I find y-coordinate? Or do I need to ?
