A y crawls from left to right along the parabola y = 24 - x"2. A spider waits at the point ( 6 , 4 ). Where is the y when the two creatures rst see each other? Hints: Draw a picture and use a tangent line of sight(pun intended). Find the slope in two ways: derivative shortcuts and rise / run. Then set the slope formulas equal and solve for the point where Spidey spots lunch
