am i doing this right?
Determine a value of the constant b so that the graph of y=x^2+bx+17 has a horizontal tangent at (2, 21+2b)
ans: y'(2)=0
y'=2x+b
0=2(2)+b
b=-4
what do u need the y-coordinate (21+2b)for?
My teacher also requires me to draw a diagram...can anybody show me a diagram of this problem?
