(i) Find ( \lim_x \to 2 f(x) ). (ii) Is ( f(x) ) continuous at ( x = 2 )? Justify. (iii) Redefine the function to make it continuous. A line passes through the points ( A(1,2) ) and ( B(3,6) )
(i) Draw a neat diagram and represent the situation. (ii) Find the height of the tower. (iii) If the angle of elevation becomes 30°, how far is the point from the tower?
(i) Find the median class. (ii) Calculate the median monthly consumption. (iii) Why is median preferred over mean in such data? (ii) Write the equation of the line in intercept form
A function is defined as: [ f(x) = \begincases \fracx^2 - 4x - 2, & x \neq 2 \ 4, & x = 2 \endcases ]
