Q4 of 149 Page 16

Write the value of if the normal to the curve y = f(x) at (x, y) is parallel to y-axis.

Given that the normal to the curve y = f(x) at (x, y) is parallel to y-axis.


We know that the slope of the y-axis is ∞.


∵ Slope of the normal = Slope of the y-axis = ∞


∴ Slope of the tangent
